hey. i searched and there is a thread almost like what i wanted however its not complete.

anybody know where i would be able to find a test pipe that has a 2.5'' inlet and 3'' outlet for my s13. thanks.

edit. any shops around me will not fab one for me "due to legal reasons" thats why i ask.

"Hispanic" muffler shops? Just tell them its for a track only car. Granted Nv has less strict laws. I'm not sure if anyone makes one like that however.

awesomenick · 08-16-2009, 08:44 AM

Why don't you just use a 3" test pipe?

3" inlet and outlet. Super common.

s13gebala · 08-16-2009, 09:16 AM

he prob has a stock dp..

lmao at the hispanic muffler shops

awesomenick · 08-16-2009, 09:58 PM

I once had a car with an SR with 3" downpipe, and a stock cat, and catback.

So I think a 3" would still work.

i have a stock downpipe going into a 3" testpipe where i bought from BING,
search for his thread. he sells them for 63 shipped + their resonated.

3" test pipe, be done with it. Flange will bolt up either way if thats what you're worried about. Doesnt matter if its 3" flange hooking up to a 2.5" flange. The measurement is the size of the opening, not the flange.

*hOngsterr* · 08-16-2009, 11:27 PM

plus you get a gasket to seal it nice and good

5t341tH · 08-16-2009, 11:37 PM

yea just use a 3" test pipe. works both ends

zenki.life · 08-17-2009, 01:42 AM

What size gasket are you using? A 2.5" gasket should seal fine, otherwise double it with a 3" gasket.

zenki.life · 08-17-2009, 10:57 AM

yea i may have to double it. im using the 2.5. but i can still feel a minor leak even with the gasket

*hOngsterr* · 08-17-2009, 02:57 PM

im running stock DP to 3" inlet and outlet to a 65mm/2.5" catback.

so signs of a leak and im using 3" gaskets not doubled .

artdrifter · 08-17-2009, 03:05 PM

just make your own gaskets. Just buy the material and trace the outline, cut it out with safety scissors and use paste to put it on. nah fo real i just cut my gaskets. u know that they will fit perfect

HAWAII · 08-17-2009, 03:12 PM

go to a welder that does gates and other crap. They do not have a " legal responsibility" on welding your test pipe. Don't go to a muffler shop.

Just go to a parts store and buy a stock gasket. While most 2.5" gaskets have a smaller outer diamater, the stock gaskets are the same as a 3" gasket, and their inner diameter is actually 2.5". That is what I used with a 2.5" header going to 3" test pipe, and had no leaks.

cool thanks guys

+1 thats what i did on my old car. i bought a high flow cat without flanges from autozone and had my neighbor weld a 2.5" flange on the inlet and 3" on the outlet. now i just rock a hollowed out oem cat.

zenki.life · 08-18-2009, 01:02 AM

yes i originally wanted to hollow out a cat. however i learned that by getting the high flow cat, you eliminate most of the C02 emissions, with flow being essentially the same. so i went with being kind with the environment. now its giving me a slight hassle. lol

*hOngsterr* · 08-18-2009, 12:44 PM

how.

i dont need you to,
you just told me

well thats why its called a high flow CAT.
so you can have the same flow bt w.o messing up the air.

zenki.life · 08-20-2009, 03:42 AM

well there are many considered "high flow" however catco is i think the highest flowing cat on the market so thats what i used. and i have work off tomorrow so as soon as i get off from school im going to do the gasket thing. thanks guys
