what can i expect with bbk long tubrs over shortys? check my sig for mods

Id say with shorties and your combo, along with a matching midpipe, you might get 15-20hp since your s/c. s/c cars seem to make more use of exhaust mods than n/a cars. if you went with l/t's and a matching midpipe, you would probably see 30-35hp gain at the wheels. MM&FF did an exhaust swap with an '03 cobra and it picked up 45+hp with BBK l/t's, midpipe, and catback. Its a bit more money, but a good bit more hp

I have to totally agree. I have seen n/a gains of 10-13 HP over factory manifolds with performance midpipe and catback.

I thought the MM&FF gain was 55 hp???

I plan on upgrading to LT's and an O/R X as soon as funds permit. I'm hoping to get close to 400 with that combo. Right now I have the stock headers, stock catted mid-pipe and a magnaflow side exhaust and she put out 374.6 with a very conservative tune.

kozumasbullitt- What numbers has your car put out so far?
