I have looked for an H pipe with the high flo cats but cant find one. Who makes one and where can i order it? Question #2 should i go with the high flo cats or no cats at all? Its an every day car and i have Borla muffs, i just dont want it to be too loud.

Any auto shop worth it's name should easily be able to fab you one.

The ONLY reason to go no cats is if you decide to run high octane. (over VP109)

Im not sure if i want to go High Flo or just cut out the cats all together. I live in Michigan and dont have to worry about tests but im just wondering how loud the car will be.

I think brenspeed has an off-road h-pipe. Anyway, Brent would know for sure.

The stocks cats are pretty high flow to begin with.

Without cats>with cats. Without cats more horsepower. With them less. Straight from the horses mouth.

Please explain to me what statistical facts or dyno charts you have to support your THEORY of losing cats = more HP. It is BS plain and simple. I challenge anyone to take a stock GT and put it on a dyno with cats, and then put it on the dyno without the cats and see a HP increase. (good luck)

hey bro here are two videos of my exhaust set-up. I have a custom made O/R. It is a very nice work because in less than 20 mins I can get my cats on or off the car. Here is a pic.

Thats a sweet video, that is just what i was looking for. Sounds nice, not too loud. Do you have a H or X pipe?

I have the stock H pipe, we just modified the section to put a straight pipe and be able to put the cats back in less than 20 mins. I forgot to let you gus know I have the borla stingers on the beast.
