borla XR-1 sportmans mufflers question
 

hey

does somebody have used these as a presilencers on your turbo rx7's? i need a presilencer because my dynomax burn out after 3 years of abuse and i was thinking to use the XR-1 sportsman round one. does anybody have other sugenstions?. thanks

YEP, thats the one I used. Made the car have a sweet DEEP rumble at idle.

I've had mine on for about 4 months in my midpipe w/single turbo setup. I use a GReddy Power Extreme for an exhaust. makes it much quieter. I believe, however, that it's starting to blow out. It's much louder. I'm going to try a Magnaflow next to see if it's any better.

I use one on my t78 rx7..takes alot of the rasp out.
