3.5" Downpipe

[TRYMY231S]

Where can I get a 3.5" Downpipe? How much do they go for? A sponser would be nice but not necessary.

TIA...

They have them for around 5 bills....i don't want to hijack your thread but who all has these 3.5 downpipes and do you have to expand your exhaust to hook it up?...i have a 3" single shot now..also how tight is it with the ac box? i am not taking out my ac but i am in the middle of putting on ported heads and have been looking at these 3.5 downpipes.............thanks Bob

Does the 3 1/2" taper back to 3" at the converter? I think the extra volume is only neccessary just after the turbo. The swirling, turbulant gas needs some room to change to a straight flow, then 3" is probably fine. Does the 3 1/2" have an intergral WG?

I have a 3.5" Terry Houston Downpipe, it fits real nice and hooks up to the standard exhaust flange. It's the same size at the 4 bolt flange. It does have the intergal wategate, very nice quality piece.

I purchased mine from Cal Hartline (Hartline Performance). Always the best prices and good customer service. He's a very reputable guy that won't steer you wrong for parts and service.

So, is there no space for a cat.? Is the pipe 3 1/2" all the way to the exaust flange, then goes to the oval 4bolt hookup?
