how is your gas mileage doing??? the last car i put them on suffered ALOT!! im looking foward to doing this mod in the near future! right after the injen ses! and lets face it, if we wanted cars that were good on gas.........we would all be driving civics! (4cyl, n/a!!!)

 

My gas mileage is about 19.5 mpg before installing them, and about 19 after, but of course I hit it harder now. One thing that is weird, I dynoed today with the Injen exhaust, and the test pipes, I was pretty dissapointed. I have to post the dyno shee when I scan it, but I gained 10 peak hp, and about 15 peak tq from my baseline dyno. I think it's the shop I'm going to, something about their dyno I don't trust. I'll try to post the dyno by tomorrow.

SWEET thats the EXACT combo im looking to run! look foward to seeing your numbers!

 

One thing, a warning. It's ****en loud, seriously. I like it, it's not ricey, nothing like that. A few have complained about the Injen exhaust being loud etc.. and with test pipes, it is even more, but I duno, I like it. Maybe I can get a sound clip tomorrow, in car and out.

My comp used to show around 23.5 mpg. About the first 3 days that I put the test pipes on, the gas milage really suffered and it seemed like when I punched it the needle would really move! lol. But now the car seems to be getting around the 20ish mpgs so not to bad, kewl beans! And pulls like a *****!

 

thats the exact note im looking for bill!! i cant wait to hear your sound clips!! you HAVE TO do a in car clip over 3000 rpms! my car LOVES anything over 3!!!

 

I'll go scan the dyno sheets now, forgot. I will take some sound clips tomorrow also, promise. I was at a performance shop here in Raleigh today, and everyone loved the way the car sounds. BRB with those dyno sheets.

 

Check out the dyno. I think something is up with their dyno. It's a Dynapack, I'm going to try to find another Dyno for a baseline, I just feel like somethings up with those #'s. Anyhow, here is the dyno, Injen exhaust, and straight pipes. Injens on there for like 3 weeks or so, maybe 600 miles, and test pipes about 2 weeks, 450 miles I'd say. Maybe this ECU is sucking up the power, who knows.

 

Where did you guys get your test pipes? I'm new to this stuffs and wonder if adding the test pipes will make the car sound too loud ?? Thanks.

 

I run a panel K&N, stock exhaust, and gutted stock cats. The car rips to redline with no power trough. It is 100% stealth with no CELs in 200 miles (Can't stop driving it). The sound is best described as a a Porsche air cooled flat six 964 RS. Love it and definitely not too loud. idle is the same. At WOT, it's a symphony.

The best I can do for a sound clip of the comparison.

Does the car resonate on the highway though?? I'm thinking of doing this mod but am afraid the car will resonate and drone on the freeway.

 

i got a sound clip from a g35 running stock exhaust with test pipes... i need a host!!!

someone contact me through e-mail or aim, my aim names are in my sig
