does anyone kno where i can get an exhuast (catback) for pretty cheap? i cant find any on ebay (maybe i m searching for the wrong thing?) and the exhaust sponsor thing for this site doesnt hav any for 4x4? any advise? i dont want to spend much more than 300$ is that possible?

 

Summit Racing.com - Dynomax Super-Turbo Cat-Back Exhaust

pretty good deal. if link doesn't work, summitracing.com part number WLK-17366

*EDIT by swartlkk* - Condensed the long link.

 

yeah, the dynomax is a really good deal, sounds better than other blazers i have heard with other cat-backs or duals. It sounds deeper than the rest.

 

I like glasspacks, most don't, but I do.

They have a nice tone to them.

 

how much is shipping on something like that dynomax?

 

looks like free shipping

 

do u know how much it might improve my gas mileage also?

 

Wouldn't expect it to do anything to your mileage...

 

y wont it do anything to gas mileage? i thought that something that made your car more efficient made it more powerful while at the same time making it consume less gas....and my friend put basically the same thing on an accord (he bought a new muffler and piping that was the same diameter as the old piping from the cat back) and now gets 4 more mpg...how does that work then?

 

Well... The major restriction on the exhaust system in our blazers is not behind the cat. Its in the exhaust manifolds, cross-over pipe, and the cat. From people that I have heard from with cat-backs behind 4.3L v6s, all they do is change the sound. No real performance or economy gains. But I'll let people here report on what they experienced with their systems.
