i had to put my h pipe with cats back on my car for emissions. Well isntead of taking the h pipe with cats on it off and crud and busting my *** cause my header studs are shot and im lucky i got them on. if after the H pipe with cats i just got rid of the mufflers and got some exhaust tubing and connected my h pipe with cats right to my tail pipes. How would that sound ya think. Would it sound like a big exhaust leak or you think it would sound good? Also would i gain or be losing horsepower or am i better off just putting my old H pipe back on with some 2 chamber flowmasters?

im running cats with no mufflers sounds awsome, i belive you have to have mufflers for smog inspection though

i already passed emissions so its all good, Anyway you can get me an exhaust sound or video clip?

Ezrider

ill see what i can do about a clip, ill have to find some way to record it (prob run a mic cable out the window of my house) mide will prob sound slightly diferent cause my exaust exits out the side of the car just behind the doors

will i loose horsepower running an H pipe with cats right to my tailpipes without mufflers?

Ezrider

no, im running 2.5 inch pipes, and the cats will give you all the back presure you need to avoid an low rpm deadspot, if you where running 3 inch pipes, id maby be conserned about not having enough back presure

anymore input from anyone else with this setup up or anyone that knows about this setup?

I've been recently running catless H-Pipes with 2 Chamber Flows, and it sounds decent enough. Running Pipes with Cats and no mufflers sound interesting, very interesting...

yeah i can't wait to try it soon.

Just remember, you don't go through emissions just once, so it might be a pain to put the mufflers on just for emissions in 2 years (that's what it is by me). But whatever you want. Wait, you do have to go through emissions again (future), don't you?
