comptech exhaust
i might be picking up a comptech catback next weekend. what i wanted to know is should i get a high flow cat for it or is it already free flowing enough?
ive seen a few people on az with high flow cats with that exhaust but is it really needed?

thanks guys can anybody else chime in too?
i know exhaust adds little to no power but whats up with that ATLP exhaust on the 2nd gen tl side. there saying its adding 10hp. hows it so different from the comptech exhaust?
im so tempted to get that but its like $950.

I have a high-flow magnaflow cat and I "felt" gains. I did not dyno it separately though and I am N/A. I also just purchased Excelerate's 2.5" inlet/outlet high flow cat, but I haven't had a chance to install it.

The high-flow cat on a 2nd gen is like a double-edged sword. You get horsepower gains on the topend but you lose quite a bit of torque on the lowend. So its not necessarily good or bad.

I remember reading that the gains from the ATLP were done on a TL-P not a TL-S.
I definately recommend getting either a high flow cat or installing a cutout ahead of it. Boost loves to flow, so your only strangling it with the stock cat.
I just got Excellerates 2.5" high flow cat as well, but I dont if Im going to use it anymore. I will need either a 3" exhaust or a cutout. We'll see.

cause he's the moderator. nuff said.
no, i mean its not like he's going 3". cause that would be a drastic change. a high flow cat isnt very drastic but he may benefit from the slight reduction in backpressure. it maybe different if he reduced the backpressure a lot (like going 3")

Lives in Boost
I'd say go for it. I have the 2.5 in/out cat and it feels free'er flowing than the RT cat before it. I don't have my stock cat but have the RT and can see if I can get a before and after dyno. I'm boosted btw

It's just not needed. Many more mods could be done with the $. If there's a gain NA it's very small. I haven't touched my cat & I dyno 252.
If you have the extra cash & want to try it go ahead but if you simply think you need to get a cat cause it's going to be such a big difference your kidding yourself.
NA that is.. If your boosted it may be a good idea.
