Just installed my 3" exhaust I got from Denny. From the moment they started it up I was very impressed...the sound is nice and deep. It is not annoying to drive around on the interstate or street. I have a pacesetter header and catless DP...there is no raspyness at all just deep throaty exhaust note. I have lost a little in the low end power, but gained in the middle to high rpm range...pulls very nice. I did not expect a 4banger to sound this good...very impressed with JBP's product and my purchase from Denny.

Got some videos up of the idle, rev, and in-car.
I will get some better ones when I get some time with the digital cam...

I'm suprised its not raspy if your running a header, catless dp, and a 3" exhaust.....

A buddy of mine has a 3 in catback on stock header and dp and its raspy when he goes WOT

 

yeah man, that is the exhaust I am looking into buying, PLEASE post vids up of it!!!!! I totally want to hear what it sounds like

 

Damn mine is raspy as hell! With a pacesetter header, 3" downpipe, 3" resonator and 2 1/2" axleback with a 2 1/2" Magnaflow muffler.

 

had mine for a year it's great. I have a JBP 3" downpipe with cat, and JBP 3" exhaust, sounds amazing really deep. I love it, but it still is alittle load on WOT

 

My set-up has 2 resonators, so it takes the raspyness out. No cat, but downpipe has a 20" resonator and the JBP set-up came with a magnaflow.

 

sounds good to me man. Did you really notice a HUGE improvement in power? and where in the powerband is it? thanks.

 

Overall the power is definitely there from 4k till redline! I did lose low end like I said, but it is actually better for traction purposes so I can launch better. I have raced my wrx buddy and pulled hard with the addition of the 3" beat him, compared to the factory exhaust we were even. I am sure the twinscrew swap will provide a positive displacement design for maximum low-end torque as well as high efficiency for maximum top-end horsepower.

 

Does anyone have the JBP header. That thing looks sick.

 

That is next on the list along with there downpipe! Heard it sounds like no other...
