You say you are running a cat, and then mention something after the cat converter...but then you say you have no cat, and it's a straight pipe?


What do you ACTUALLY have?

[Gtseviper]

ok....straight pipe in place of the cat...2.5 at the end of the straight pipe all the way back...magnaflow resonator and muffer included

Aside from Schrödinger's cat, adding a second resonator will help, you could also remove the muffler and add stainless steel wool to the intake side (used to do this back in the day, but be advised, it will add a little restriction). Chore boy works great, just stuff some in there and try it until you find an sound/performance ratio you're comfortable with.

would it be better to replace the straight pipe with a cat or just a short resononator

[visualpoet]

Either would help.

high flow cat and a second resonator

why not get a silencer that goes to your tip of your muffler you can make one but idk, you need a stainless steel plate good size enough for your muffler tip, and screw three or two holes in your muffler to hold up the silencer, i did this to mine cuz my Carbon fiber muffler has a loud deep tone, and with the intake installed it sreams deep!!!!...but with the silencer it sound like a normal noise level but you still get your same tone of noise....

on a stock setup...high flow cat won't benefit you, waste of money. If you are turbo or built engine then a WELL BUILT high flow is best...cheapos are a waste of money.

You NEED the cat, a resonator, and a long big muffler to quiet down.

check the muffler bearings too

i find magnaflows to be very loud. id invest in a big chambered muffler.

Ditch that straight pipe and get a cat. I got my exhaust off eBay, had the "test pipe" on it, it was loud as shit, put the stock cat back on, its way quieter, sounds like stock exhaust, even with a fart can for a muffler. But I still get the benefit of having 2.25 inch exhaust with a header. The ONLY time it's loud is if I down shift, then its a nice, deep tone

[Gtseviper]

alright cool...stock cat it is...I was hoping someone had an answer like this one...

[Gtseviper]

alright problem solved but I learned the hard way..the cat is on and I remove the magnaflow muffler and went back to my dynomax turbo muffler...quiet as hell now
thanks for your help fellars

with no resonator or aftermarket resonator will still be loud though i mean louder than the stock being there.
