the best exhaust for horsepower

[Jlock8]

which exhaust adds the most horsepower and sounds good? and do headers add horsepower? if so, which one add the most?

[OOLIE]

Exhaust don't expect much, but a catback may add a few. Shorty headers will give a decent amount and Longtubes will double them roughly. Maybe 25 with LT's

[Jlock8]

will LT's sound good with a catback?

[lscamaro]

LT's will make the car sound raspy which can be alleviated with a magnaflow resonated x-pipe. i hear the ark catback has no rasp with lt's but I have never heard it myself. I currently have borla and am getting bbk's in a few weeks. Another person that owns my exhaust said it was rasp free so I guess we will see lol

I would just add, most exhaust are designed for the stock manifolds. when you add the additional flow you throw off the sound of the exhaust. Magnaflow mufflers are very low sound mufflers and really don't sound that well IMO, until matched with additional flow. I don't know what your goals are, but I willl say Magnaflow mufflers with Magnaflow x pipe, and LT's is a nice combo. If you can go OBX (without cats), Magnaflow res x, and magnaflow exhaust that is the cheapest way to get power without cats. it was like 675 for parts max, which included shipping.

Exhaust sound is a personal opionion. We recommend you hear a few and decide what you like. You won't get much power out of a catbac if any. The real power gains are made with replacing the factory cats and or manifolds. A set of high flow cats is a nice option as is long tube headers. They will change the sound some on their own and increase the volume for sure. We have tons of options at our site most with video and killer deals on full systems in our power package catagory. Check it out.

that's my video, what i heard LT headers give u +30 hp and catback give u more power than axle-back exhaust.

Not trying to be a jerk, but aren't the real power gains in the long tube headers themselves. High flow cats are better than the stock option I agree. Is there any dyno info on cats themselves?

I have just the MRT 1.0 with an Injen intake on my 2LT, sounds very aggressive. Great rumble at idle.

i wish more people can get a ride with me, or even drive my car. corsa catback and bbk longtubes, no rasp, no drone. I mean, if there is, it's so minimal that you couldn't tell. Might be a bit pricey for some, but then you don't have to worry about adding xpipes or worry about any of the added drone, etc.

he did say "and or" manifolds.

[bill2129]

Cat back more like 6-8hp. Long tubes close to 10-15. Don't buy into the crazy numbers sites claim. On a stock car you wont get 25hp. Stock headers flow to good on modern cars. With a old carb motor you can pick 25 up easy
