Hey guys its been a long time since I posted since my firebird has been down since last February and will be till winter. Anyways I got a magnaflow on it and drove it for about 150 miles and hated it. So I may have it sold to someone and I am looking into a new exhaust. I am wanting something a little bit louder since the stock exhaust sounded better than the magnaflow. So I am looking into maybe a slp loudmouth or making a true dual setup. What would you guys recommend. I am also looking for some rasp. Some hate it, I love it. For the guys with true duals how hard was it so setup.

 

True duals with X pipe. No substitute when coupled to longtubes. X pipe kit from Jegs or Summit is a great start and leaves room for a pair of high flow cats if you need them in your area or cutouts if you want them. Your choice of mufflers after the X. Some do Dynomax bullets, some do glasspacks, some do a single chamber or 2 chamber muffler. My current project "red car" is getting Pacesetter 2239s, 3" to X, 2.5" back to a pair of Dynomax Ultraflow Welded mufflers, 45* turndowns. Weirdo X pipe I got from TorqueTech last year pinches the rear part of the X from 3 to 2.5" and been dying to use it.

 

i dont have true duals, but
i just removed my catalytic converter and put a single 3inch mandrel bent catback with a thrush muffler on, its pretty loud, definetly louder than the flowmaster si/do i had on it.. it has more rasp to it also, it definetly flows better than the flowmaster si/do did..

 

GMMG, sounds fantastic, and it's loud

 

Yeah But I am a poor college student that has dropped every dime he owns trying to get this car running again. In the last 18 months the engine was taken apart 2 times then rebuilt. Then it blew up. So some more money for another engine. That along with 3 bad clutches. And to finish it all my t-56 is finished off thanks to a bad input shaft bearing. 1/4 inch of play is a little to much. Would love to have it but can't afford it.

 

True duals with no crossover if you want rasp

 

i used to have duals with no crossover and they didnt rasp at all, SLP louthmouth will rasp like a SOB and scream at WOT

 

The Loudmouth is your best option in my opinion. They can be found for cheap and they're loud as hell. True duals are a nice idea but to be built right and have decent clearance they will cost way more. Plus with the Loudmouth if you decide down the road that it's too loud you just change the muffler.

 

used borla?

 

my 3inch thrush muffler cost $40, the 3inch mandrel bent pipe come from autozone from a commercial sales person through a friends business, the pipe cost 90.00 it was a Vortex brand pipe.. muffler shop bolted up the pipe and installed muffler and tailpipe for $30..


i cant believe its 2010 and no one around me has a mandrel bender.

 

What about the TSP Rumbler catback? Its cheap loud and raspy.

 

magnaflowster

 

This or loudmouth.

No cats and longtubes will help as well.

 

Yeah the car has some longtube headers and an off road y-pipe. I might end up getting my buddies slp loudmouth. He is going to a true dual setup and will not be needing it. If all else fails and the magnaflow does not sell ill cut the i-pipe up and put in a cutout.

 

Borla or Loudmouth for rasp.

 

My current setup is in my sig but I'm debating running a true dual setup next year once the motor mods start coming. My thought was to run an X-pipe with two Powerstick chambered mufflers with turn downs. It should be pretty loud. I ran the same mufflers on my IROC and man, shook the windows in my house just idling. Powersticks are the cheap alternative to the GMMG.

 

Loudmouth or just weld a pipes violator behind the axle with a hidden tailpipe. Will be loud and rasssspy.

 

anything with a y pipe is going to be raspy compared to true duals

 

go true duals or put a 18inch bullet on instead of a normal muffler. It will be loud at idle and scream at WOT. also save a few lbs too.
