Has anyone ever tried this on here before? I was playing around with my friends mustang and the idea kinda hit me all of a sudden. I've heard our cars with full exhausts and they sound good. I can't even imagine what true duals would sound like on our cars. Think it'd be even possible to make a true dual setup on these cars?
*waste of time* a good 3" single shot from the cat-back will work great, that is what i have and i love it, expect around 10 hp from that and about another 10 if you get a test pipe. and then about 15 whp if you get full length headers, you can get some good gains from exhaust mods.
I dont think a test pipe gives you 10hp, but I might be wrong.I got the catback exhaust and the test pipe and intake and I dont feel 20hp gain.
Test pipe + cat back on my NA netted less than 10whp.
True duals would sound like ass on our cars unless you had a crossover pipe somewhere in there. It would probably sound close to a Honda (1.5L 3 cylinder X 2). If you do a crossover and/or had something to change the exhaust note (like turbos) then it would probably sound decent, but then you get in to the fact that you just added a bit of weight that will negate most the power you just gained.
Yeah thats what i was thinking too. Instead of a downpipe, just have the headers to a xpipe to two mufflers and tips. I'd assume it'd sound deep and probably really loud. I've never looked under my car to much yet is there room for an x pipe?
hey this is gd25's friend. I have a 94 firebird that uses a piece of shit single exhaust coming out of a y-pipe. bassani makes a true dual setup for the f bodies that has two pipes running parallel to eachother in place of a larger single pipe. they exit in the same spot as factory, unlike most other true duals for f bodies that dump just before the rear axle. this is the same concept I was thinking of for a 3000GT, I have not seen the underside of one but if the exhaust were to come down off the manifolds, go into an X or H pipe, then into a bullet style muffler (one for each exhaust pipe) and out the back of the car, would it improve sound/performance at all? I have heard many fbodies and true duals sound BY FAR much more aggressive. true duals do not add too much weight. two 2.5" pipes will flow similar to a single 4" pipe, the weight difference between the two isnt too great.
a test between a borla 3" single exhaust (a very good flowing exhaust) and a bassani true duals yielded a gain of 14 hp and 12 ft lbs of torque recorded at the rear wheels.
just curious if similar gains could be had on a 3000GT
A dual exhaust could work out well... the thing is that the few who have actually tried it here have done wrong. If you're going with a dual exhaust on an NA, you can't go with 2.5 or 3 inch piping. That decreases exhaust velocity waaay too much. I think that well-muffled 2.0-2.25" dual exhaust would perform / sound awsome. I think that the costs outweight the benefits by far, but money aside, a well-tuned dual should outperform a single.
