Muffler

I cut off my muffler/ exhaust after the cat tonight, what a difference! It always felt like my timing was off, it would sputter when i first got on the gas. It is fine now, so much more responsiveness, i cant wait to run dm and see if it was what was holding back my boost. I would always get 2-4 lbs less than what i set it at, wg actuator as short as it would go. Sounds pretty good too, rumbles my ass:lol: I may post a pic of that massive thing i cut off, and maybe a sound clip of the new setup.

Re: Muffler

Let's see and hear it!!! Thinking about doing the same thing prior to deciding on the right muffler to buy.

Re: Muffler

I am running a high flow cat and no muffler. To me it sounds perfect.

Re: Muffler

I have a cutout before the cat and muffler, and throttle response is awesome, but it sounds like crap at wot.

Re: Muffler

I was going to go with a cutout before the cat, but I may just unbolt my ATR cat back exhaust once I get the new motor in. That sounds pretty mean. Does it drone a lot and give you a headache when cruising?

Re: Muffler

Re: Muffler

I have 3" after the dp/cat, just like 2 ft of it. High flow magnaflow cat I think. It does have some drone, but only above like 2500 rpm. Sounds badass at low rpms and idle, has some great pickup too, scared a bunch of people at an outdoor restaurant tonight just getting up to like 2k rpm from a little jolt at idle. Seems to improve my mileage, but I may just be thinking that, lol. Sounds like a loud ass v6 with open headers at WOT, isn't as nice as lower rpms.
Edit: it rumbles like a bitch, between idle and 2k rpm the mirrors are fuzzy, lol. Just FYI for anyone concerned about how legal it is noise wise, I was reading high 70-low 80 decibels walking around the truck at idle. got into high 90s right at the pipe cut off, but from what I've heard they are supposed to read it from like 15ft behind the tailpipe. Most have told me 85db is limit here, dunno if its the same in other places. above like 1500 rpm its high 80s from right beside the truck, so its pushin it.

Do you know what the full system to the back will do to change the sound from just the cut off muffler setup? I know cops around here look for pipes more than they listen for mufflers.

Re: Muffler

I had ny exhaust off and was just running a DP for a while. That was too loud for me. The cat and pipe takes away the raspy sound. At idle it sounds like a stock v8 mustang to me. wot people say I have a v8 in it.

I raced that sti before. With just a2a and a stage 1 turbo. I took him off the line but he overtook me at 80mph. This time I have the heads and a stage 2. should be a close race. We are going to 0-120.
