Do you have to have a h-pipe? It'd probably come out cheaper to just go to an exhaust shop, have them cut the y-pipe off and run pipes down each side connecting to the catback.

Re: trying to switch from y pipe to H pipe

Dennyray, that system will bolton to the stock y-pipe coming from the cats. That system shouldn't require any welding or cutting. If you do go with a y-pipe kit, i'd go with a Pypes brand one. Its cheaper and sounds good on the six.

If you want "true" dual, you can buy a h-pipe adapter kit or have a shop weld straight pipes to your cats. You could also buy a stock GT exhaust and swap the mufflers for better ones.

There are a million choices you can go through. I went through pretty much a different exhaust setup every year when I had my V6. My last setup was an offroad X pipe with flowtech afterburners and 24inch long 3 1/2 inch stainless tips.

Re: trying to switch from y pipe to H pipe

you wont make any noticable power from going to an h pipe. Even if the H pipe has no cats it wont matter much. Most just cut off the stock Y pipe where it goes into one pipe and run a new pipe on each side. You do not need a balancer pipe (the middle of the H) on a v6 as its an even fire motor.

Re: trying to switch from y pipe to H pipe

I was not aware that MAC made a Y-pipe? Or was this something an exhaust shop did for you? I had a MAC Off-Road H-pipe, however had some high flow cats welded onto it and then just bought some flowmaster 40 series mufflers and I got lucky and found some new GT tailpipes for $75, but you could have anyone make you tailpipes for around that price. Too many exhaust systems to choose from and I had flowmasters before and I love the way they sound on top of them being a low $ exhaust system.

I think he is referring to the factory-stock v6 y-pipe

Re: trying to switch from y pipe to H pipe

I took mine to a local shop had them cut out the y and run true duals with flow 40's for 300.00 Like Brandon said it's a even fire motor you don't need a crossover or balancer pipe

Price sounds about right (If the price included mufflers)
