im trying to find whats a good exhaust setup for a good low price. i was looking at an off road x-pipe w/ flowmasters 40 series and w/ bbk shortie headers.
how does this setup sound ?

Would have a higher pitch due to the X pipe VS if it was an H Pipe. Then again you never know b/c I have a catted X pipe on mine and it sounds mean as hell. Ive got an O/R H that Im going to need to get rid of.
 
save your money and get a spintech exhaust system. dr gas makes the best o/r x pipes on the market. go to www.drgas.com and look at their x pipes for mustangs. their shorty x pipes look way different than all the rest and their design is far superior than the rest. the crossover is as close to the engine as possible and it really does make a difference in power and in sound. as far as mufflers they are all pretty close in power output. i perfer spintech over the flowmasters cause ive had both and the spintechs sound a little more aggressive.

I completely agree! Before my turbo I ran BBK longtubes, dr. gas x, and spintech pro streets. It sounded sick!
 
The pro streets are the louder ones and honestly with tailpipes they were a little bit too quiet for me. They sounded sick without tailpipes, but there was a bit too much drone so I threw some tailpipes on. It still screamed from the outside but it was pretty tame from the inside. I guess to most people that is perfect. The tailpipes also made the sound alot cleaner which is nice. I guess what I am saying is to get the optimal sound from them you need to run tails, and I am thinking the Sportsmans would be too quiet since the Pro Streets were not overly loud with tails. Get the Pros!!:nice:

Btw, if you are going to get Spintechs they offer a kit that includes mufflers and flo-tubes so you don't have to have a shop weld in extra piping in between. If you buy that kit a standard tailpipe kit will bolt right onto it. I think the mufflers/flo tubes kit was $160.
 
also please get the dr gas x pipe. fwiw, i had flowmasters on my car and switched to the spintechs both with tail pipes and my car is louder with the spintechs then with the flowmasters. i have the prostreets.

How much more power? Can you prove it? What, if any, power gain would you see on a 302, maybe 2?

When buying the exhaust for street car, I've come to the following:

1 - Buy long tube headers.
2 - Buy a "high flow" cat system, its not worth the aggravation of swapping pipes for inspection.
3 - For a 302, don't debate X, H, or Prochamber for power reasons, do it for sound. The power difference is negligible, but you'll hear it forever.
4 - Dumps sound terrible.
5 - Multichamber mufflers will drone. Its the nature of the beast. Some are better or worse at this, but most of your typical 2 chamber "muscle car" sounding mufflers are going to drone on you.
6 - YouTube and sites like it are your friend for samples. Also go to carshows and ask people what they are running to get ideas.
7 - The phrase "screams at high RPMS" is terrible, everything screams at high rpms. You're driving a mustang, you'll be at "high RPMS" rarely. Get something that sounds great from 1000 to 2500. Thats where 99 percent of your driving will be.

i can tell you this, a friend of mine with a 91gt with an edelbrock hci, rpm intake, and a holman moody custom cam picked up 8 rwhp by switching to the dr gas x pipe over an h pipe. both was with longtubes. go to www.drgas.com and read the articles that explain the differences and benefits of their x pipes.
 
im still looking for an o/r x-pipe but i dont want to spend alot. i was looking at PYPES x-pipe and heard good reviews about it. i wouldnt mind going for an h-pipe but it doesnt flow the gases out faster compared to an x-pipe. i want a good deep rumbling, hell on earths ound but also gains at the same time. i now have a double chamber flowmasters catback and bbk shorties. plus i have stocks cats on for the moment.

Sorry Adam I have to take issue with a few of these based on my experience:

2- My car drones with my high flow cats on it... I remove it for sound...
4- DUMPS ROCK Period... I love how my car sounds...
5- My car does not drone at all. Get gears to get our of the 1800-2000 RPM range and no more drone.

So as you can see everyone has an opinion... I think this year I am going to try and put an x-pipe on it to get a different sound. been running the H for 3 years now...

The pypes setup comes in 3 pieces. Personally I prefer the single piece units for leak prevention and ease of install. Something to think about.

fastgtfairlane: Your friend payed for dyno time just because he swapped from an offroad H pipe to an offroad X pipe? And there was 8rwhp gain? I want to see the dyno runs for that before I believe it.

I would believe that if he switched from an H pipe with cats to an X pipe without cats.
