would it kill your torque if you had three inch...

[TheBlackSwordsMan]

yea they leak if cause they have ****ty gaskets i am just gonna get em to weld the sucker on.

[blackbyrd]

good solution [img]graemlins/thumbsup.gif[/img]

hey there is alwasy duct tape lol

[TheBlackSwordsMan]

Yea but weld lasts longer lol.

[blackbyrd]

stop laughing at me lol

did you get waht i said about that 2.75inch y pipe from suncoastcreations for $245 its made for the v 8 though i wonder if it would fit

[TheBlackSwordsMan]

I don't know, it probally won't though. Most people have to get a custom y-pipe made.

[blackbyrd]

yeah dont know that many places that could do that though

[TheBlackSwordsMan]

Me either that's why i am gettin a set of headers with the y-pipe hehe. [img]graemlins/burnout.gif[/img] [img]graemlins/rofl.gif[/img]

when putting on a 3" catback, you'l still have a fair amount of low-end torque since the stock cat outlet diameter is 2.25". I believe that the y-pipe from the headers is 3" since the cat inlet is 3". To lower the torque peak, just add intake mods to the car to get more air into the cylinders.

[blackbyrd]

do you know what diameter the y pipe is from them
i think someone said that the one that comes with the cia headers is 3 inch's the pictures look it but looks are deceiving.

[TheBlackSwordsMan]

Email them and find out. Artic the y-pipe i think is either 2.25 or 2.5, its 2 somethin is all i can tell you, you could prob find out by searching for it. The collector outlet is 3 inches and the cat inlet is 3 and 2.25 out

arctc wolf
the inlet of the cat is 3 inch but the y pipe collecter where the pipe form the manifolds comes in isnt just by looking at it i havent measured it at a guess i might say it looks like 2.5 if that it is not very big compared to the 3 inlet on the cat. but i may be wrong cause i have no exact measurments.

[blackbyrd]

so 2.5 or 3 if i go with 2.5 i can get it made at an exhaust shop near where i live but if 3 im gonna have to figure out something else. but just the thought of having the 3 inch is driving me nuts cause i know what a difference it made from the cat to the muffler and im missing the s bend. which i plan on replacing when i do this and a high flow cat. i just need some info on which would be better and a safe bet i dont really want to loose my low end torque but for the sound i might be worth it.

[Arctc Wolf]

ok, so you have 2.5" collectors into a 3' y into a 3" inlet/2.25" outlet.

[blackbyrd]

stock, i believe it is less than 2.5 from the manifolds to the collector which is 3 inch to the cat, which has a 3 inch inlet and a 2.25 outlet.

i want to go three inch all the way from manifolds to muffler
(already have three inch past the converter to muffler with 2.5 outlet)
keeping the 2.5 outlet from the muffler

[blackbyrd]

ok im going with the 3 inch cause the stock y pipe isnt bigger than 2.5 more like 2.25. so im gonna get the pipe to make it from jcwhitney get a couple of 90 degree bends one straight and a y collector. get a high flow cat 3 in/out then the 3 inch s bend to connect to my existing 3 inch i pipe. this should sound great but i hope my low end doesnt suffer to bad. thanks for your help
