Hey,
I got a custom 2.5" mandrel bent b-pipe (non-resonated) installed on my car last week, with a stillen rear section. People claimed only about 4hp gains.... Haven't dynoed my max or anything, but even with my 18's, with the clutch fully released, if I were to punch the gas in first, I get crazy wheel spin. Anyone dyno their max after b-pipe. My mods are pretty simple engine wise, just intake, no cat, bpipe, stillen rear, and some stickers for added hp, jk. The car seems to pull MUCH harder. Maybe its just me.....any thoughts?

 

From what I have read here on the org the complete catback gives our cars around 6-8 more horsepower give or take a horse. This is the reason I decided to just keep my OEM catback for now. I have thought about the resonated Warpspeed B-pipe in the past, it is about $150 or so for people who have bought their Y-pipes. I like my car on the quieter side.

How much louder is your car now?

 

some people say that unresonated is way too loud, others like it. It all depends on you, but in my opinion my max is not loud at all, but VERY deep. It all depends on the set up you are running. if you have stock muffler it really doesn't matter. Im running test pipe cat custom b and custom stillen muffler from a 2k max. My max sounds smooth.

 

Thanks for anwering my question. Maybe after the holidays I may rethink about the last bottle neck in my system(B-pipe).
