mid-pipe

[01silver freak]

im lookin for a new or used off road x-pipe for 03 gt i guess brand doesnt really matter somthing to get ride of the stocker sound besides flowmasters

I absolutly love magnaflow products, great build quality and sound. Their catted X-pipe makes teh same power as their O/R acctually.

The best O/R pipe however is a Dr. Gas if they are still made, they always had the best power of them all.

MAC Pro-Chamber

price range i dunno 150-250 roughly but wouldnt say a pypes mid pipe put out the same hp as say slp both being 2.5 in piping? in theory i would think so cause they are just pipe

I've really enjoyed the sound out of my MAC H Pipe.. but I'm going to have to be looking for something new pretty soon myself =( i REALLY need to find something that tucks under the car better =(

just my 2 cents here.. i have found that an h-pipe, on a dyno and at the track, delivered 20 rwhp more than an x-pipe.. and gained 80 rwhp by taking flowmasters off and installing straight thru mufflers, i have the dynomax welded mufflers 2.5 inlet and outlet, they open up to 3 inch inside the muffler.. where as manaflows reduce the pipe size inside muffler, but are still good mufflers.. if you have a stock car x-pipe works great.. if your car is modified go with h-pipe and straight thru mufflers.. stay away from chambered mufflers, unless you prefer the sound over hp..

80rwhp? That's unbelievable.

positive.. i also had a supercharger at the time with 10psi boost.. thats why the gain was so impressive.. you cannot have to big of pipe or too much exhaust flow with supercharger.. more flow the better.. probably wouldn't have seen that much gain with a na motor..

I've had a blown car, and swapping from crappy stock exhaust to a nice flowing 2.5" mandrel bent system with straight through mufflers didn't net me nearly that much power. Hence the reason I asked if you had the dyno graphs. I'm not saying it couldn't happen, I'd just like to see what the graphs looked like.

[goofy]

like i said the graphs are at "appalachian performance" in black mountain.. i'll get copies of them and post them sometime soon.. you don't have to believe me.. it doesn't matter.. each car is different, and i know what difference it made to my car.. the flowmasters would not let enough exhaust flow to reach the hp that i get with straight thru mufflers.. exhaust makes a big difference on a SUPERCHARGED car.. you should know that........

[goofy]

here's the graphs

[goofy]

started at 350 rwhp.. changed exhaust 431 rwhp first pull before tune.. have to change maf to 90mm to get more hp.. pegs stock 80mm..
