talk to HvRRZ (Ruben). He dynoed his single N/A with 3 inch with decent gains. He posted his and emailed me his dyno. I asked him alot of questions before I did the same thing.

 

did a before and after dyno of another member's car in illinois with invidia. did 3 dyno runs before and 3 dyno runs after. taking the highest of each set, he made 6rwhp. after adding the test pipe to the invidia, he made another 11rwhp, for a total of 17rwhp.

a decent exhaust does provide gains for our car. test pipe is a great bang for buck mod.

 

that's a nice gain on the testpipe. that is good to know.

 

^ I just had my valves adjusted earlier this week and the mechanic, who works on a lot of S2000s drove my car afterwards and was in shock as to how hard it pulled. I have no doubt that it's because of my test pipe/exhaust.

 

Something was definitely wrong.

 

yeaaaaaaaaaaaah...a s2k is not beating a C4 vette...
