Well sort of a what should I get for the best gains kind of question...

Right now I have the RS*R Exmag GT2 catback exhaust and just a cone filter up front...

My plans are to get the AAM plenum spacer and AAM test pipes...I was wondering which should I get first and get the most gains???

I've searched and found claimed 10whp gain from the plenum spacer but I couldnt find anything on the Test pipes.

Any O2 anyone????

 

Test pipes are simply an open pipe with nothing inside. Besides fit an finish, I cant see one brand being “better” than the other.

 

Test Pipes = bad if you want a decent exhaust sound.

 

So the test pipes would eff up my exhaust note??? hmmmm i love the way it sounds now..I wonder how if would effect it...Does anyone have the RS*R and test pipes????

What im looking for is the power gains...not really the different types of TPs out there...i just cant find any dyno numbers...can anyone point me in the right direction???

 

rsr is loud already and with test pipes it might be annoying loud, not nice loud. However, i'd suggest getting resonated test pipes for a nice race car type sound. eseially w/ the RSR. Laboree, kinetix or megan are all good. I had megans and i liked them. Just be prepared for a stinky garage

 

LOL yeah i heard about the smell...thats no biggy tho...wont last forever so its not going to kill me..i think lol...How is megans quality? i know Labrees are up there in price and good quality...kinetix is somewhere in between right?

 

Test pipes will make your car VERY loud. With my Nismo exhaust which is quieter then your exhaust I expect. It made my car 10x louder. I have a set of test pipes I will sell you for 50.00 + shipping if you want =)
They are Helix non-resonated.

 

The megans i had were fine. The whole "megan sucks" thing.. most of them crack b/c of some fitment issues and install issues with aftermarket exhaust(Nismo and Fujitsubo mostly). I had mien and they were good. Fit fine cept it was a little close to the passanger side body..but like had a 2-3cm gap..so i was fine with that. Sound..it was def louder lol.
