onebadmax Posted October 9, 2013 Report Share Posted October 9, 2013 Honestly, if that's your only mod, I wouldn't do it. If you go with. LTs you will be way happier. High flow or no cats with LTs doesn't matter no real difference. Quote Link to comment Share on other sites More sharing options...

diggerdan11 Posted October 9, 2013 Report Share Posted October 9, 2013 I would just stay legal and vet high flow cats. No cats = bad smell = risking cops pulling you over and getting a ticket. Quote Link to comment Share on other sites More sharing options...
canadianVRss Posted October 9, 2013 Report Share Posted October 9, 2013 (edited) Smell, yes, rasp easily taken care of. Drone, that's the real problem, if your cammed. Edited October 9, 2013 by canadianVRss (see edit history) Quote Link to comment Share on other sites More sharing options...

Blown 346 Posted October 15, 2013 Report Share Posted October 15, 2013 Rasp is the high tone that sounds like the exhaust noise goes all over the place. IMO it sounds like crap. Quote Link to comment Share on other sites More sharing options...
misterp Posted October 15, 2013 Report Share Posted October 15, 2013 Removing the cats will only gain a tenth of a MPH in the 1/4-mile on a Radix-blown truck; the gains on a naturally aspirated truck are even less. Flowmaster is not my personal choice for muffler... it would be interesting to see what the truck runs in the 1/4-m without it. If you really like the sound then keep it, but there are a couple "straight thru" products that perform better. The best sounding exhaust I've had, and EVERYONE complimented both on the street and at the SSS truck meets, was factory manifolds + gutted cats + Corsa Touring + 2800-RPM converter + CAI + tune = pure sex. Focus on the tune; in the Phoenix area it shouldn't be too hard to find a couple guys that can really tune that truck WELL. After that, if you want more performance you will want to focus on transmission improvements, that can cut an easy 3-5 tenths off your time. After that .... ???? ;) Mr. P.

misterp Posted October 21, 2013 Report Share Posted October 21, 2013 You're going to have to ask that as a new topic, under the PCM TUNING sub-forum. Also ask on CorvetteForum.com, and LS1Tech.com etc. Mr. P. Quote Link to comment Share on other sites More sharing options...
