FAT-35T

Hey guys. I just got an exhaust on my xr6t. Its a single 3inch to cat into dual 2.5inch. All stainless steel.(the guy at the exhaust shop said that this was the way to go for performance instead of a straight 3inch). What you guys think.Oh and what sort of power do you's think ill be getting.

Cheers

Why didn't you save your money, and just get a big ger cat??

Single 3" is smaller than stock, so if you wanted a gain over stock, you would need 4". Dual 2.5 is bigger than single 3".. The cat might flow more, it might not. Different mufflers may give a marginal gain. It will sound faster tho.

Its possible you will lose power, not gain. The std exhaust is very good and doesnt really need to be changed until you get some serious power.

I know of one person who removed their cat at 250rwkw and gained 25rwkw.
They then replaced the stock exhaust minus cat with the APS exhaust and gained another 10rwkw.

If people think the stock exhaust isn't restrictive at 250rwkw then they need to do some more research

Fine then if he has modded his T already to that power level but if his first mod is an exhaust he's gonna gain about 2/10's of not much and possibly spend alot of money for a disappointing result, let alone overboost issues.

Yes, I agree. You must accompany a larger exhaust with a unichip or otherwise to handle the overboost issues and ramp up the power

You are right about the power limit of the std exhaust. Mine is at 245rwkw and have had injectors and springs done but I cant get anymore until I either do exhaust and/or cat or both.

Is yours a manual??

Check this out..



Very good friend of mine. Manual with 968's, stock exhaust, cai, springs to go in.. + edit..

Yes, he could change the exhaust and gain some more kw, but the 5sp will self destruct as it is. My point is, depending on how far you want to go, exhaust might not be here nor there nor beneficial.

Now, if he's just walked in, got an exhaust and nothing else, yes he may have gone backwards, and the guy should have informed him accordingly..

Get a Unichip/Edit, and your exhaust $$ will be justified, until then, I'm with the others, gain will be negligable..


As far as the stock exhaust being restrictive, yes it is, it has to be, it's a piece of pipe. Every exhaust is restrictice, at one point, BUT does he want to get to the point where the exhaust becomes an issue.. Well, he bought one, so I dunno??? and that's not what this thread is about..

My T is an Auto. You say springs to go in because it looks like valve bounce may be evident. Good numbers and I have seen similiar power or better with those mods in Auto too. Mine just stopped pretty much, couldnt get any more power.

Strange, what's causing it to 'just stop'.. something has to not take effect, ie fuel,boost or timing, which one didn't make any difference? Might help in problem solving??


Which injectors did u go for? any idea on duty cyle??
