hey whats up what, what do you htink the real hp gains are with my topspeed testpipes and greddyevo2 exhaust and does any1 have any sound clips of res test pipes along with the evo2 exhaust i havent installed mine yet

 

hmm im thinking anywhere from 15-20 for sure. those test pipes alone would give u like 9-12. so. is the greddy evo 2 a catback system? if yes, it might even give better gains. a y pipe back system doesnt really give great gains.

 

nice so the stock whp is what like 260whp

 

yea. 1st gen sedans are 260. but the 2nd gens are 280. what year is ur car

 

i have a 2003 coupe

 

I dnt really know. I Have a sedan

 

honestly, don't listen to anyone here about possible gains...which is why I won't give you a number. The ONLY way to tell is to do a before and after dyno session. I'm not trying to be a d*ck, I just hate hearing inflated claims.

 

After I installed test pipes, I actually think I lost power. They weigh a lot less than cats and the bracket, but that was my only gain.

Also the car now smells bad. I also sounds like *** @ 3500 rpm. I want to take them off, but don't have time to deal with it right now.

 

Genearally TP will tend to decrease low end torque, which is probably the reason you think you have lost power. They do however tend to increase high RPM power.

The smell is normal with TP, there's nothing you can do about that....same with the rasp you hear between 3k and 4k. There's pros and cons to everything, you just have to find out what you can/can't live with.

 

true

 

I just bought resonated test pipes and I'm afraid to install them. I hate rasp.

 

What type did you end up getting? If they are resonated then it really should only be raspy between 3 and 4k RPM.....unfortunately, that's where the majority of daily driving occurs!

 

That's why HFC's are so nice, same power gains (unless you are going forced induction) and your torque doesn't fall out.

 

idk man i have topspeed res test pipes and i didnt feel any drop if anyhting a lil more punch in the low end i cnat wait to see how my greddy evo2 sounds with them

 

i have evo 2 with res test pipes and there is ZERO rasp and its a perfect tone not too loud and not ricey at all...

i am impressed with the clean crisp sound the evo2 puts out...
