hello my jet hot long tube install is complete,anyway my car felt a little less torquey and the sound is a little different than when i had the edelbrock shortys.so my question is i have jet hot long tubes into a custom 4inch y pipe going into a 3 inch flowmaster cat back what is a great flowing muffler to replace the flowmaster muffler with and sounds nice and deep it sounds a little raspy now. thank you

 

Sounds right. You've lost it from decreasing backpressure, which is good. You just need some power adders.

 

Everyone says how bad a flowmaster is because of the baffels in them.

Has anyone had them on a dyno on a modded car with a different catback that is "better flowing" as a comparison ??? I was jsut wondering how big a difference it could make on a stock, lightly modded, and a modded, say heads cam headers car ...

 

Just get a cutout.

 

i do have a cut out it is just to loud to leave open all the time at least with the shortys it was

 

Our setups are real close.
I run the HotCam also, with alot of bolt-ons. I have Jethot LT's into a Mufflex y-pipe, and into a 3" Hooker Catback. I use a Flowtech cut out at the track. Just by addind this exhaust, I gained 40 RWHP. I recommened the Hooker. Do a search and alot of people on here have said only good things about it.

 

so i think i will go with the hooker muffler any part numbers and good place to buy one?thanks

 

i heard the hookers rust because theyre aluminum
but since you're in florida, i guess you wouldnt have too much of a problem
its a different scenario up here in ohio

 

Dig through these see what you find you might like. I installed the Dynatech 3" Silencer Cones yesterday from Summit Racing. They don't do squat for taming the beast sound with the afterheader dual 3" cutouts...BUT! they did deepen the Borla a little more without affecting backpressure whatsoever. Longtubes tend to affect every catback system because they were designed to work with stock pre-cat exhaust systems. Trial & Error to adjust them from there.
