Haha Sharky, do a swap

 

With 900+ hp, do you really think you would notice an additional 15-20 hp (2% more power)?

No I should have mentioned that I don't notice anything these days... Actually the thing I notice on my car the most is going from cats to no cats

 

Amen brutha!!!

Guys while on topic of cats, i was told i have no cats when picking up the car and never even thought of even looking. So i decided to actually look and i see that i have cats but that are gutted, should i just throw straight pipes on or will it not even be noticeable, any negative of having the actual cats but being gutted?

 

you''ll eventually throw a CEL but I wouldn't worry about it.. Just reset it. Without cats you'll have less back pressure, less lag and more power. Oh and a bit more boost too However if you went to straight pipes from what you have now you'll be VERY loud indeed.

 

So even right now im considered as having cats, and my backpressure isnt reduced and i dont have the same effect as just having straight pipes im assuming? I notice from inside with my evo exhaust its quiet and can drone, but from outside at WOT it is LOUDDD, i let a friend drive it and i had no idea how loud it really was, but its an amazing loud, hmm..

Alex what im wondering is, having the no cats now it probably aplified the exhaust alot already, would doing muffler bypass pipes or cat bypass pipes be similar just a little louder?

I guess what im trying to say is, lets say i had evo exhaust and cats, i removed cats and became WAY louder, would it be even more of a jump removing muffler bypass or cats to straight pipes, or am i already tolerating the loudness that people would hate? Hard to explain, sorry to confuse you!

If you have no cats and have not set of the CEL I sounds like the parameters have been changed in the ECU.

 

Yes i do have tuning to bypass the CEL
