Running a Racing Beat single tip with an unresonated midpipe or a hollowed Cat?

Im trying to decide if its worth buying a resonated midpipe or just hollowing out my cat..

I had a friend running an Apexi N1 with a straight midpipe and it was deafeningly loud even following behind... so id like to keep the noise level decent, hence the Racing Beat, but im wondering how loud itll be with a straight midpipe/hollowed cat, versus a resonated midpipe...

any input would be helpful!

 

hollow the cat and if you dont like it buy a midpipe. try something with what you have first before spending money. hope you ported the wastgate and have a boost controller before just bolting up a full exhaust.

 

buy an rx7store resonated midpipe.

the exhaust will be quite loud without a resonator

(i had the RB single tip with a hiflow cat in the midpipe and it was still loud)

 

I bought a used "mint-looking" dual tip RB catback from a forum member and my car is raspy and loud...it only sounds nice under bridges at wide open throttle. That's with no cat. A friend installed a previous generation dual tip RB catback on his car, with and without a cat, and it is significantly quieter than mine. I condemn the packing in my muffler and I even spoke to Racing Beat about this. They think it's unusual that the stainless packing would have blown out, but possible. By design they should have a nice exhaust note with or without a cat. A resonated midpipe will definitely bring it down even more, but it's subjective, so it's hard to say what you would find acceptable or unacceptable.

 

the turbos im running (hopefully) are stock twins with a BNR wastegate already installed and im running a PFC as well the turbos are in Non sequential.

eitherway, im trying to find the quietest route without suffocating my engine...

 

i have the racing beat single tip and it was extremly loud so I put a magnaflow in the midpipe and now sounds great.

 

hrm... maybe i should hollow the actual cat out of the piping and just weld in a magnaflow?

 

thats my exact setup

racing beat single tip
3" midpipe

it sounds decent. and amazing at WOT

 

straight midpipe, no resonation?

how loud is it at cruise? im looking for a set up thats bareable when im cruising.

 

Theres a dude paying $125 for cats in the 3rd gen fs section, dont just smash it all up! Use the $125 for a used midpipe or for the magnaflow you were talking about.

 

yeah i might do that.
