Replace the resonator with a magnaflow SS x-pipe, now it really sounds good when you nail it.:dancing

Re: name that catback
 

Wow, thanks very much for the responses. Glad to have it ID'ed for real.

Funny thing is with the headers, cats and no resonator it's got a pretty vicious drone. Great sound at WOT gets lots of compliments at the autocross events, from everyone except the sound marshal :(; problem is the tips aren't very friendly for trying to add turndowns or a baffle though so an over-limit ends my day.

I haven't noticed any difference in the sound but I have been running with the same club for a couple of years, then two events back-to-back get warned or called on sound. It could easily have been simply the conditions but it occurred to me that if it was a glass-pack type design it could be burning out although other systems I've had did the telltale 20' "tail" of cloth coming out of the pipes LOL.

As to weight, well every pound matters and I'm starting at a disadvantage (guess all those cams are pretty heavy LOL). On the other hand, low and at the rear are the perfect place to stash some pork.

I found a nice little straight-through muffler that I could add upstream, cheap and light enough, but maybe I'll wait and see if I get called out by the meter again. It's really good to know for sure what I'm starting with though. And maybe if it is degrading, I'll gain a couple of those ponies back...

Thanks,

Re: name that catback
 

I'd like to try the X pipe but I've been told by several to stay away for resonance reasons.

Do you have resonance?

Re: name that catback
 

Ran the borlas with straight pipes right up to Watson small tubes No resonators. No drone at all, Might be worth the 5-10 hp...

Re: name that catback
 

How loud ? What size pipes?

Re: name that catback
 

Mine was very loud, 2 1/2" pipes. Had a guy with headers on his z over and his eyes bugged out when he heard how loud mine was.
Sure miss that car.
