I'd like to get a cat-back exhaust system to replace the stock one for my 94 Z. I'm trying to decide between SLP loudmouth or a Flowmaster system.... flowmaster would cost a little less but if the loudmouth system sounds/performs a lot better, I'll go with that.

Opinions please? And when I do decide, what's the best place to buy it online?

 

Loudmouth...Flowmaster is restrictive...I have had both, I wouldn't buy the flowmaster unless I was going for sound. Performance though would be the loudmouth...But the Loudmouth does sound great!!

 

loudmouth sounds ok if you have cats, but if you ever do longtubes and no cats it sounds raspy like an ls1. I'd also at least look at Corsa or Borla, they both have a deeper, richer tone. don't get me wrong loudmouth sounds good just has a raspy sound without cats.

 

Yeah, I experienced that....I did a cam and LTs at the same time....It sounded bad at WOT....put cats on it....Man, worlds apart in the sound quality... Still friggin loud tho...Being stopped 3 times in less than a week would be testament to that...I experienced that too...

 

Out of the two,,,i vote for Loudmouth. although EVERYONE in the world practically owns one, or so it seems...theres probably a good reason for it... They like it!
