Important Exhaust

AIght, i called mac performance to order a Offroad H-Pipe and a dual cat back exhaust, The person said its a waste, it sounds like crap and does nothing for performance, they said that i could get minimally 20 horses if i get the direct fit dual for my stock y-pipe, and buy the straight shot intake. Doing this would save me like 50 bucks. WOndering if im being played or is this person true. any information on the perfomance changes with the direct fit and new intake would be helpful.

doing true dual exhaust pays off once you do more performance or if you plan on doing more performance. i personally dont like the sound of v6 stangs w/o cats it just doesnt do it for me with exhaust and no cats or with cats your definitely not going to see anywhere around 20hp you'll definitely be looking at single digits

That is probably the biggest load of POOP I have heard in at least week. There is no 20 HP in any Exhaust and CAI PERIOD!!!!! There is like 0-3 HP gain in exhaust with a stock engine and around 3- 5 hp gain with a CAI. Any bigger claims and you should run away as fast as you can. The reason for dual exhaust on a stock V6 is for sound. A O/R H pipe is a waste on a stock V^ and it sound sort of crappy. You are best getting a custom dual exhaust at a muffler shop or by a dual exhaust kit.

Oh the person on the phone was a TARD

I agree also, that guy was a tard. I personally don't like the custom made dual exhaust kits made by mufflers shops. I had one and it was nice but wasn't good for what I needed. It's a single unit that is welded from front to back and the only way to remove it is to cut it in pieces. I went with the O/R H-pipe and the Cobra take-offs because it is a completely bolt-on kit. This way I can remove a section of my exhaust like the h-pipe if I need to. It's not like I remove my exhaust frequently, but I just like having the option available in the future if I decide to go something different and not have to cut up my current exhaust to install a new one. This allows me to keep my old exhaust still in a "sell-able" condition if that makes any sense. Also, if you have the old y-pipe there is a 1/4" steel rod to help support the tranny. This really gets in the way if you can not remove your exhaust pipes from the car. That's my take on it.

I personally would just because of what I stated above, but this will cost you slightly more. A custom unit will run you probably about $350 with the mufflers of your choice installed. A bolt on unit will run you probably about $400 if you went with an O/R h-pipe, and obviously more if you went an h-pipe with hi-flo cats. About $200 more to be exact.

Edit: I mis-read your post. If you do decide to go with the direct fit exhaust you're pretty much saying you're done modifing your car. If you have any other plans of seriously modifing it, I would HIGHLY recommend again getting it.
