Re: Exhaust question
"Can" type, expansion mufflers are the only 'real' mufflers that have any hope of keeping the sound level legal and at the same time offer some honest horsepower gains at the same time.
Flow thru "Glasspack" types are generally doomed to sound like your local hospital's neonatal ward with 200 infants all in full cry. They are so bad that even the manufacturers (those that care and recognize the problem) of these flow-thru types offer silencer inserts to bring their product into compliance. Unfortunately, these are effective only because they restrict the exhaust tip's outlet; thus negating any 'real' power increases that 'might' have been realized.

Re: Exhaust question
well its not a glasspack, its an extreme which is a can type (http://www.jegs.com/p/Cherry-Bomb/Ch...67133/10002/-1). but the guy at the shop is going to kind of hold up both types of exhaust and rev the engine so that i can decide which i like better. but do you think that i should put in a full 2.25 cat-back system if my 2" pipes are still good? will it really change anything?

Re: Exhaust question
Yeah, reason I chose to go 2.5" piping is because of the H22. The H needs the piping to be opened up to really respond. I can definitely tell that it pulls much harder; otherwise, I would stay 2.25" and not waste any money if I was still single cam.

Re: Exhaust question
Sorry to drag back up the thread, but im working on my exhaust right now and figured I could do with some advice...
I have my heart set on an Apexi WS2 muffler based on reccomendations here.. I would go the catback route but seeing as I'm taking it out of the country, the muffler is the only real option that can fit in a suitcase..
Anyway, I current have an AEM intake, stock exhaust , stock header...
I purchased my DC sports 4-2-1 header and its ready to go on but I don't have the Apexi muffler yet (and wont for months)..
First question is:
1. Will I see any benefit of adding the header onto the system without doing any actual exhaust upgrades as yet..
2. Where do you all think the true restriction in the exhaust system exists, is it in the 2" piping (i'm NA just starting modding, don't plan to turbo at this moment)
Or is it at the stock muffler barrel.. I don't have a cat to worry about as my model never came with one here in Trinidad
If it is the muffler, I can have that changed without too much problem,
If it is the actual 2" exhaust, then I need my exhaust shop to make me a custom catback.. Would the upgrade to 2.25" really justify the cost in my case? At this moment I really only plan on I/H/E and Bisimoto Level 2 cams with corresponding head work
3. Would the DC sports 4-2-1 fit under the stock honda f22/f20 heatshield? If so, should I worry about thermal wrapping it..
If it cannot fit, once again should I thermal wrap it? I know it increases the risk of rusting, but I do not need any other factors increasing heat soak via my SRI
Thanks for all the help in advance! Glad to have this forum as a resource..

IMO for smog legality and anti-fart-can sounds, AEM CAI, DC sports header and RS-R exhaust.
This combination on a '95 EX 2.2 is quieter than the stock exhaust at idle.

DC sports headers come in stainless or coated, and I would not wrap a coated header. Nor try to fit a heat shield to said header.

Re: Exhaust question
Thanks for the replies NUSS and Mike,
Carried the vehicle to the exhaust shop today, apparently the "leak" on the stock exhaust barrel is more like it rotting with rust.. Gotta change the barrel and buying a "stock" like barrel is about $120USD here, which pushes me in the direction of an upgrade to the Apexi WS2 for about ~210 or so..
So, as it turns out, the start of the exhaust system for this vehicle is 2" but that doesnt last long.. apparently its really 1.75" going most of the way back.. Thus, pushing me toward an upgrade of the entire exhaust..
The same exhaust shop told me to do the entire exhaust from the flex pipe back (no cat here) would be $2300 TT Dollars, aka $365 USD, not counting the cost of a new barrel..
This definitely has sent me in the direction of ordering the entire catback system.. Of course, seeing as I don't have a cat I will still have to pay for a small piece of pipe to connect that to the flexpipe..
My problem is this, when coming back to Trinidad, I normally bring parts in my suitcase, eg. rotors, intake, exhuast barrel etc, but a catback is a new level of large..
So what I am asking is this, anyone who has ordered the Apexi WS2 catback, how does it ship, ie. in how many pieces, and what is the longest piece? Do you also know the weight of the entire catback system? Hoping its under 50lbs.. and the longest pipe is no longer than about 3 feet..
Concerning my DC sports header, it is ceramic coated.. but why not fit the stock heat shield? If I remove the shield I think that I would be facing futher heat soak problems via my intake..
Same goes, why not wrap a coated header? Rust concerns?
Thanks

Re: Exhaust question
I'd buy a whole new system from a dealer that can sell parts internationally. While i have never had to order internationally, most places that do that much shipping get a discounted rate to keep end user cost down. When most exhausts come in they are in one box that i would say is about 3.5ft in length and 2.5 ft wide depending what model you are ordering for. As far as the heat soak... I dont have any issues (h22 dc header) and have not used the shield for the last 3 years. Hope this is some help to you.

Re: Exhaust question
Thanks for the suggestion but if I order to Trinidad, then I have to pay taxes.. which jumps my price another 35% or so not counting the increased freight...
If what you are saying for the box size is right, I'm sure I could make it work in my suitcase, even if I have to pay overweight charges on it..
Reason I asked about heat soak, it is a horrible problem right now and is severly limiting performance, so much so that im considering going back to the stock intake.. Will this completely cancel the gains I could see from the header and exhaust? I have yet to identify whether the heat soak is a pipe problem or the filter element taking in hot air..
I am lead to believe it is a problem of the intake pipe overheating, as the filter element sits only 5" or so away from where the stock underhood intake was..
I'm thinking, that unless I can solve this, I may experiment with slapping the filter onto the stock intake piping.. or I could try using some reflective heat wrap on the intake piping possibly?

Re: Exhaust question
Well, I already own DC 4-2-1 header, just havent put it on yet... Also, what is the diameter of the f22b1 and b2 exhaust piping in the US? Is it like mine where it starts 2" but goes down to 1.75 when it reaches the resonators..
Also, does your model have 2 resonators? I suspect this is going to be the main exhaust restriction, hence why i'm thinking of the Apexi ws2 catback..
I would really appreciate if I could get some advice on how the apexi ws2 ships, if anyone knows the size of the various lengths of pipe etc...
Thanks

Re: Exhaust question
Ok, spoke to one of the companies that sells the exhaust system...
RaceInspired: weighing 57 lbs
Size: 66" x 12" x 20"
So, the maximum length of checked baggage is 62", to any of you who have ordered it, do you know if the box is the exact size of the lengths of pipe or is there a few inches packaging room, ie. bringing it under my maximum transport size...
Thanks

Re: Exhaust question
when i got my cat back, it came in 3 pieces, and the box was a little larger than the actual exhaust itself. it comes in a huge box, but the exhaust itself does not take up the whole box.

Re: Exhaust question
This might sound ridiculous but I finally settle on the Apexi WS2 and I order it only to find out that its out of stock and backordered from Apexi.. Seems like they have some supply issues again...
Such a let down because now I will have to wait months before I can take it back to the caribbean with me!
I have a mind to cancel the order and spend the money on something else right now

Re: Exhaust question
Honestly, I set my mind on the WS2 because I understand it to be quieter than the Greddy, plus its cheaper..
Well, most other sites will run me about $75 more than the site I was ordering from.
I'll keep my eye on the alternatives but worst case I just have to hold on for them to get the stock..

Re: Exhaust question
well the whole point was to try and save some much needed $$.. I don't want to cheap out on parts I use.. I just like to get it as cheap as I can and buying it from streetrays will save me something like $100...
I'll find a way to get this exhaust home to Trinidad regardless of what it takes..

Re: Exhaust question
Hi everyone,
So I finally got my WS2
Basically the situation is this.. I was planning to bring my exhaust home (Trinidad) with me as checked luggage in its various parts...
I called/emailed both Apexi and the retailers and it seems like no one could give me accurate dimensions of how long each piece was...
http://www.apexi-usa.com/content/pdf6191.pdf
Basically, its 3 pieces..
The middle piece is no problem, that fits in my suitcase....
The front portion, I can also transport that as a piece of luggage without too much trouble..
The main issue is the back pipe including the exhaust barrel.. The maximum dimensions allowed for the flight is 62 inches, the total of this comes up to about 68 so that isn't a realistic option..
So my question is this, looking at the schematic, say I was to cut the pipe section leading to the barrel with a clean cut, it would save me almost 20 inches, meaning I could take all the parts home with no issue..
WOULD DOING THIS AFFECT THE PERFORMANCE OF MY EXHAUST OR MAKE INSTALLATION SIGNIFICANTLY HARDER IF IT HAS TO BE WELDED BACK TOGETHER IN TRINIDAD.
ALSO, WILL DOING THIS WELDING AFFECT THE SOUND AND AIR FLOW OF THE EXHAUST?
Hopefully I can figure this out within the next few days before I head home

Re: Exhaust question
Someone? Anyone? Its time sensitive, im flying in 3 days...
I was thinking to use a pipe cutter and make a clean cut on the straight piece of the back pipe.. Please let me know what you experts with more experience think...
