Hey everyone, I'm no expert at modding my car but I love to street race people and bring my car to the track every once in a awhile. What would be the next thing to do with the current mods I have now?

Mr99SS

LT1-4's like to breath , the flowmaster muffler has a lot of back pressure

CodieG95

So should I X pipe it and dual it or just get a different muffler for a ypipe?

Mr99SS

x pipe with duals with 4 inch would be ideal but that cost $$$ .... Id change out the muffler for now with your currant hp.

my brothers 96 Callaway GS supernatural has no muffler and its not really all that loud

CodieG95

what would be a good muffler to get? also Id rather it be louder.

Mr99SS

slp loud mouth if u like loud

CodieG95

would there be any loud mufflers that can connect to a y-pipe? because all ive seen SLP is bullet

You want a full catback with a 3" mandrel bent intermediate pipe. That's where you will find a meaningfull power increase. If you are planning on more engine mods in the future, consider the Mufflex 3-1/2" or 4" catback with the Flowmaster 30-series race muffler.

what about the flowmaster 10 series?

Mr99SS

im not into the series ... 10 series the 2 chambers ?

CodieG95

10 series has 1 chamber I believe.

The Mufflex system comes with the Race Series. I pushed 800HP through the 4" catback, with no problems. I deleted it to save weight, and went to a pair of 3" Borla XR1's bolted to the collectors, and 3" pipes to the rear axle with turndowns. We were unable to measure any significant HP difference between the Mufflex catback and the Borla duals. A buddy of mine put over 900HP through the Mufflex 4'.

Mufflex also offers Magnaflow and Spintech.
