Question about exhaust

[SleeperMx6]

I just took off my exhaust. The only exhaust I have is the downpipe and it has a tendency to backfire every once in a while. Was wondering if it would still do that if I put 2.5 inch full exhaust without a cat.

I have a full exhaust... cat, resonator and factory muffler and I can get a backfire when I zip through a gear or two. It sounds nothing like what you are probably hearing but I know it's a backfire... more like a "PUFF!" than a "BANG!" Make sense? :lol:

I ran downpipe for quite a while, just got the rest of hte exhaust today... I noticed while I downshift I had a popping backfiring noise... its just hella muffled now cant even tell.

I think it would still backfire. After I got rid of my cat my car backfires sometimes when I let off the throttle, and it does on every 1/4 mile pass while I'm decellerating hard.

I don't know I think I just might have exhaust pros make me an exhaust, Its sounds like a monster truck with a TURBY!

Do they pressbend it?

[SleeperMx6]

Yeah they do press bend but its better then stock and cheaper than mandrill bend. (If thats how you spell it)

[Jim]

You should just save enough for mandrel bent (they can weld the bends together), you'll regret pressbent...

I agree w/ Jim on this one, have someone weld you up an exhaust using mandrel bends. Caleb @ Type-R did mine, but I am positive any of the shops in town would be more than capable of handling your request for that.
