I posted on ephatch about getting a stock midpipe so i can get some pricing on getting a few mandrel pipes made but no one is helping....maybe because i dont post much there.

Does anyone here have a stock midpipe i can "borrow" (READ--not buy) to get the correct dimensions. thanks in advance if you can help.

If you were in SoCal, I could lend you the midpipe to a custom one bent. Why can't you just take your midpipe off and have them use that to measure?

 

tommorow i go to get my midpipe bent for the si. As for getting some mandrel bent pipes for the si talk to kteller he has a whole setup for 180 bucks mandrel bent.

 

I drive my car everyday and do not have time to send out if needed. What i was going to do is ship to an exhaust manufacuturer and have make and price out two pipes. One stainless, one alumunized and see what everyone thinks. If it looks good than order a batch up.

if you pay for round-trip shipping then yes, you can "borrow" mine

 

i dont have a problem with that, my zip is 08028 if you would like to see how much....i appriciate your help....if no one comes through by mid week we will set it up

 

why settle for mid pipe, i could do you a full mandrel bent catback, 2.25 2.5" or 3" for you guys!

Because the midpipe is all you really "need". Several dynos (including one done
by Yack/B18CXR) show that the stock muffler/axle back flows fine, but that the
midpipe is the true holdup.

That said, if you can give us a price on a custom cat-back, I know I'd be interested.
You'd probably find a semi-decent amount of buyers for something like that, provided it has decent gains and that it is under $300 (Magnaflow's catback is
~$275 and has a decent dyno-shown gain).

 

go to his store he has great deals and good work my friend bought a cat back from him and he likes it alot

because unless your boosting, the factory can flows just fine

[only change between the two runs was removal of the factory can]

 

wasnt someone talking about doing titanium midpipes at one point?

what size would you guys be interested in doing?
right now i offer the catback piping, which you can use your current can:
2.25 or 2.5 in mild steel and in SS
its everything in a full mandrel catback but the muffler: If you guys wanted i could work something up for this forum only: If someone is intersted: let me know, via pm or email.

 

People are saying a 2" mandrel-bent or 2.25" crush-bent is optimal, and any bigger is a waste.

2.25" is the size I like

 

Jimmie...Eric has one at his house! It's mine now, but it's still there. I was supposed to pick it up to bring to Jimmy at Monro, but if you can find us a mandrel bent one, then you can have it instead. It's in his backyard, just give him a call...or just go there and get it.

 

good i will pick it up this week and get started on this mandrel bent one

 

get my number from eric...get TWO(2) made aight man. wait...is your number still the same?

so he gained like 1 tq only with removal of the can?
I dont see the green power line anywhere? did that not change is that why?
sorry i just dont think i see everything , your showing???

 

You can barely make out the green line (2nd
run) in that dyno. Barely.
But it lies almost exactly on top of the base (1st) run -
so by that dyno, removing the OEM muffler
does absolutely nothing for performance. So
our stock muffler flows just fine.

ditto, thanks

 

Anytime, Jack - thanks to you for the dyno and good research!!!

ok now i am more confused then ever.. i asked why go with a midpipe only and now a full catback, say like 2.25? With your stock piping size and it being stock/crush.... youd figure you could gain some out of a good system? You said to just replace the midpipe?

you proved that even without the muffler it flows the same?

did that dyno have a midpipe? or just a stock system with and without the muffler?

cause that still dont answer my question as why would you get only a mid pipe? and not full piping?

sorry its 4 am here,

i understanding why you wouldnt change out the muffler..

I think what Jack is trying to say is that there really isn't a need to change out the factory muffler because the stock one flows pretty well. I think in the dyno run he used a 2.25 b-pipe with the stock muffler on the first run, and then he took off the muffler in the second run. In the graph, it shows very little difference.

Sorry if I'm not clear, I have a headache and it's late.

thats what i thought, but in a catback you dotn change out just the muffler.. thats what i dont get.. no one is trying to change just the muffler..


Jack, did you do a dyno with all the piping replaced and the stock muffler

the muffler we can somewhat tell is good enough, i am was referring to the stock piping... why not replace all the piping~

Yes thats what he did.

Its a back to back dyno of 2.25" b-pipe and stock can and 2.25" b-pipe with no can.
