is there a brand that makes a 3inch cat back system for a 97-01 prelude? all i can find is 2.5in! i found some 3in piping for my lude but i want the whole kit with out header. thanks for the help

 

I was recently looking for a 3" for my turbo build and was referred to kteller

You'll have to supply a universal muffler and weld it though

 

what cat should i use that works good?

 

I haven't planned that far yet ... I'll be running open dp for the time being ...

I'm also in the process of building an H2B with the old H22 from my 'lude, so I have a lot of bits and pieces in the air right now ...

 

k teller 3" kit. +1

 

well let me ask this....what cat would you use if you where to pick one i plan on supercharging the lude not sure if that makes a difference in what cat i should use.

 

just have a shop make one... aspec has good mufflers that dont break the bank. and can find them on ebay too from there shop for like 170 at the most.
p.s. dont hate on ebay its good if you know what your looking for

 

I haven't even searched it out yet, I figured I would just start searching for brands that make a 3" high flow cat, then I would see who is using them on here and what their impressions are.

That would lead me to different brands, and I would compare them all based on technical information available, specific features [comes with flanges, for example], member impressions, and price.

I'll probably end up welding proper flanges on instead of just welding it in, so that I can replace it easily if I have problems.

So the short answer is I'll research, then I'll do some trial and error ...

Sorry I don't have anything for you right now, I wish I did, cause that would be another piece answered in my puzzle.

 

no prob man that seems like what iam ganna have to do i was just wondering if you already new thank you

 

Running a 3" magnaflow spun-cell cat here; $100 and a solid performer. Running it obd2 and no problems with cel's.

 

If you have plans on running a real EMS and not a piggyback just convert to OBD1 and don't use a cat, less money in the end.

 

well i plan on getting a jrsc at some point. iam gonna need to tune it so could i just go p28 obd1 and leave it at that

 

I got the Kteller 3" inch exhaust , no cat or silencer and 3" inlet magnaflow muffler, it's very loud, I guess I didn't feel any gains since I didn't tune it. I guess I'm getting old but I wouldn't want that as a daily driver, hopefully a high flow cat and a couple of silencers would make it sound nice.

 

well i would use a cat not sure about a silencer though. not even sure of a muffler tip i wanna use

 

Lol, hear you on that one. I have a 3" with cat and a borla muffler and it was really loud. I threw in an 18" vibrant resonator and it's at least streetable, but still pretty loud, and it is my daily. Sometime down the road I'll probably add in another 12" vibrant resonator (all that will fit).

Anyone doing 3", consider yourself warned and understand that when everyone says a 3" exhaust is loud, it really is loud.

 

I think 3"+ is a hazard of boost, if you're not boosted or heavily modified N/A, I don't see the purpose in going bigger than 2.5". I think is what most of the cat-backs for the Prelude out there are.

From what I understand, you can actually loose power/acceleration with an exhaust that's too large because the scavenging effect is reduced which can leave unburnt fuel and heated air in the chamber.

 

there are dynos on here showing the stock h22 loves 3" exhaust

 

That's surprising to me, does it gain through the entire power band or are there losses in the low end? I would think at low-mid RPMs there would be losses, I would love to see a dyno of a stock H on 3" exhaust.

I'm not being contradictory, I'm interested.

 

there are man under faq its a sticky thread. click under the 3inch exhaust if i remember right the prelude that did it just had some bolt ons nothing major

 

ok i tried to copy and paste it all in here for you to see but if you read the above post you can find it all under the faq sticky thread and go under exhaust. its not bone stock but it just has simple bolt ons

 

Good to know, I knew I was going 3" with the boost, so I never looked.

 

lol i wanna go with 3inch also but my car is lowered about 2 1/2 inches so i dont no i guess iam gonna try it out

 

it's through the entire power band. i was shocked when i saw it

 

well, dude wasn't stock, but not THAT much more horsepower. and of course, you have to tune

well you should tune no matter what, and the only bolt ons the guy had was a crap dc header witch is like no hp gain. a short ram intake, cam gears that gives you no hp he didnt specify rather or not he advanced them or not so iam guessing they where just installed and he took out the 2ndary butterfly. thats almost stock, stock block, stock head factory intake manifold,factory tb,factory fuel rail and injectors and still made good numbers with a 3inch piping. now if i would not go put 3inch piping on b16 or somthing like that. i wasnt a skeptical at first to but the graph shows he gained 5hp a 24 ft lbs of tq. and thats what iam after is tq. iam hope fully ganna have a jrsc soon so a 3inch should do me good
