i am used to rx7 hookups i need a little help here. I am doing a beginner setup of injen cai and injen cat back / rear axle back exhaust and i just purchased a set of mmw headers with an s pipe i was reading a post saying that setup will make the car sound like a 92 civic with a auto zone muffler tip. Will i need a resonator or what
HELP

 

Most likely it will sound raspy. I know a lot of people on here use Magnaflow resonators, which size, im not sure, someone else will probably be able to chime in on that.

 

Yup pick up 1 or maybe even 2 resonators or a "Straight Through Muffler" to take down that rasp and get your exhaust down to a nice deep rumble.

 

appreciate the info...what inch size should i get for the resonators i saw different ones on dezod's website. Also i just got off of the phone with pro-motion tuning and they said with my header setup i would have to remove the catalytic converter is that true is there a way around that . Emissions and all

 

I purchased the MMW header and I haven't recieved it yet. I'll prob. keep the midpipe and just get the Precision Muffler axle back.

Their website. For the price I think it's worth it.
