Jus read a bit about the Mufflex 4in cat backs and was wondering do you think it would be worth it over the 3in SLP LM i have if i had a custom 3in ory-pipe made for my BBK shorties?

I don't think that it would be worth a lot to you especially with shorty headers. You would need long tubes, 3 inch Y pipe and be making some serious HP, like in a forced induction car.

Unless you're running a high cube motor and need a lot of topend power, a 3in exhaust should be fine. The only real situations I can see a 4in exhaust being adequate in would be an autocross type event... the topend advantage that a 4in copuld provide would be advantagious in an autocross, or roda racing event, imo. then again, i'm drunk as **** typing this post, so i wouldn't take me totally seriously in this state pf mind.

take this post for what it's worht.

Save the 4" for forced induction

ROFLMAO at the drunk remark. Thanks guys, i was jus curious. I think the most ill be doing w/ this LT1 is maybe a 305 or 306 cam but i definately want LTs soon. Im goin to FMS to get it tuned pretty soon and addin a crank pully and 52mm TB & hopefully some Pace LTs and 3in ory. I have a Jasper re-built motor in it now but i dunno what all was done to it over a stock re-build besides a .030 overbore to 355c.i. and 3 angle valve job on the heads. the previous owner ran 13.1@ 108mph w/ 3.42 gears. Best of 3 runs, said he kept boggin down ( i know its true cuz he video taped it) on a 2.2 60ft using 275/60 BFG DRs on 15x8in rims and 15x4in skinnes ( Convo Pros) w/ just bolt-ons ( except TB, pulley, and EWP) stock suspension besides SFCs and LCAs & the 1 5/8in shorty BBKs running open so maybe there is a lil more to this motor than i know about cuz the car prolly weighs at least 3500lbs w/ driver. Id figure you need around 310-320rwhp to hit that trap at 3500-3600lbs unless ur light as hell. What do yall think?

I don't know why more poeple don't consider 3.5" as the perfect compromise.

My friend got a Jasper engine in his Z..... Jasper engines are stock engines.... just rebuilt. The reason he got one is because when Firestone worked on his car, some one dropped a bolt into the engine and went BOOM BITCH BOOM!!!! So firestone had to replace it,they called up Jasper engines and bought it from them..... SO its stock....

Ah, thank you hawk07! Feel better knowing. I guess the shop that put the motor in did the .030 to a 355c.i. and supposedly did a 3 angle valve job on the heads. All i know is this car ran 13.1@108mph( not to shabby) on a 2.2-2.3 60ft so its got 12sec potential. Didnt see it run in person but saw a video of it
