anybody running testpipes on the Hr motor? im considering getting testpipes on my 07 nstead of high flow cats. I heard from a couple guys running testpipes that they noticed a deff increase in power. any info would be helpful thanks.
Yea I'm running aam test pipes with the aam single exhaust and yea I def noticed a increase in my top end but having such a free flowing exhaust I lost some of my low end torque. Honestly I'd say spend the extra money and get hfcs its not worth the few extra hp to put up with the rasp and not to mention emissions.
so im prob gonna go with Stillen HFCs. maybe eventually nismo headers and exhaust but my local nissan dealership said that hes not pullin the nismo headers up on the computer for an 07. anybody running nismo headers?
