Right now I'm running 3" from the DP to the muffler. That's it...no cat, and no pre-silencer, or resonator. As you can imagine the car is loud as hell. What would you all suggest as a means to quite it down? I'm running twins and the car is full Non-Seq.

ThanX

 

A resonator will help a lot. However, in the end, "the end" will play a big role in the sound. i.e. if you have an Apexi exhaust, it's going to be loud with or without a resonator. It will be quieter with the resonator, but still loud compared to most other exhausts.

 

I ran a Magnaflow exhaust in the midpipe on my last setup with the Apexi N1 at the end. Still pretty loud but much quieter than having a strait-pipe.

 

get a racing beat duel tip exhaust.. they are nice and low with a resonator but they get loud at wot... friend of mine has it with a boral resonator <- if thats how you spell it.. sounds nice.

 

I'd have to second the RB dual tip and resonator. I've got that setup, and it's very mild sounding, but still rumbles, at lower rpm's. When I give it wot, though, it gets as loud as I'll ever want a car to sound.

 

I have only a dp, stock cat, and Racing Beat dual. The sounds put a bigass smile on my face. I guess I'm easy.

 

I used to have DP,MP w/out resonator, and Blitz CB. It was definately screaming loud. I hated it.

I then bought an rx7store resonated midpipe with a racing beat dual tip. So i basically had 2 resonators on the car, and it sounded perfect. Nice quiet tone at idle and everyday driving (kept local authorities away), but screamed at WOT.


Here's a video of my dyno last year, you can compare the difference.

Mahjik is very right. The end does play a huge role in it. Right now I'm running the stock twins sequential no resonator, no cats, just straight pipe all the way back to a re-amemiya dolphin tail. And it sounds beautiful. Even at full throttle its great.
