My current exhaust set up on my 95 6sp Z28 is JBA shorties w/ jba y-pipe and flowmaster exhaust. I just ordered the Mac 1 5/8s mid length hedders w/ ORY, and SLP dynomouth as well as an ASP crank pulley. Will i see a noticable difference by changing to this new exhaust set and crank pulley? Any input would be helpful. Also would a mailorder tune/ HPP3 tuning tool be just as good as a dyno tune or should i just get a dyno tune? Thanks guys!

 

Well if anyone cared to know, i just put on the dynomouth in place of the flowmaster exhaust and WOW!!!!!!!!!!!!!!!!!! I love it I highly recommend the dynomouth ...its sounds so awesome!

 

What ever you do.... DO NOT get the HPP3 programmer... THEY SUX.... Best you can get is a dyno tune.....

 

Or check out PCMforless. They do "mail in" tuning. Supposed to be the next best thing to a dyno tune.

 

Ive decided on a dyno tune for sure!
