I've heard of people using two resonators in their exhaust system. I think it sounds like a good idea. I'd like to hear from anyone who has done this.

I have a 98 ITR with a jrsc at 8 psi. I already have a kamikaze header with the 2.5" collector, but I need to decide on the rest of my exhaust system before I have it installed. I'm definitely going 2.5" all the way, but I need to keep it as quiet as possible. Any suggestions would be appreciated. Thanks

 

I had the HKS Hiper system on my 98 civ, it has double resonators, beautiful sounding, it was constantly turning heads. I traded the car in and bought my Type R , and used the civic Hiper exhaust (had to cut it 2 inches) and it sounded just as beautiful on the ITR. I still had the Hiper once I went boost, but ended up with a Thermal 3 inch, which sounds phenomenal plus it breathes better with the larger piping.

To sum it up, I loved the HKS, it had dual resonators, sounded fantastic, great performance. Just do it.

 

Well, if you plan to run straight pipe, it's a good idea, that's what we did on out CTR, we just ran striaght pipe, but to meet the 103bd level required for SCCA, we had to add two little tube style resinators.

If you're planning on using a muffler, you're really better of with just one, although I guess it depends on what you want to accomplish. Keep in mind, the more resinators, the more restriction, and therefor less hp. Any way you slice it, your car won't be that loud under boost, you'll probably hear the charger over the exhaust....

Later,
