Sell the wife :shrug: j/j

I have a UPR-x and magnaflow weld in mufflers. About 300 all together. My best with this set-up is 12.916 @ 108.63 and dynoed 296.8 rwhp and 320.1 tq. It don't sound the best but it is makeing good power. Bill

I have a upr x pipe and I have the same sound. checked and everything was tight. My cat back is stock with magnaflow weld ins. My car still makes good power I think its because the x pipe is not made that good. could be wrong? but my car dynoed 296 rwhp and 320.1 t with my set-up.

I would also like to find out about the UPR pipe
