Strange exaust ideas...
 

I need a new cat-bact setup. I recently blew the seam on the right muffler completely apart, after that the muffler broke off of the pipe. I was wondering if I could see anything in gains or losses of power by going single pipe. I was going to cut off everything after the cat and have the stock exit diameter of the cat carried back to a muffler on the left. I'm just trying to get out of a noise ticket, and wondered if this'll be quiet enough(well, also any power changes). :rlaugh: Anyway, any ideas on muffler choices, or if I should carry it out on the right instead of the left? I just see so many drifters do it this way, I figured there was a reason. Any help is greatly appreciated.

well the lnly way your gonna get more power is if you take the cats off. putting new pipes after the cats wont do much. i took em both off and replaced em with an exhaust i made. it is a lil louder but not enough to alert the fuzz. if you replace the header as well you will definately feel a power increase.

I'm still trying to get around a noise ticket, though. Power isn't main goal, quieter than having my right muffler completely severed AND blown apart is. Just wondered if a single pipe will be enough.

yes a single pipe with a muffler should be enough. you could just fabticate a y-pipe and a mufdfler for the right side. i built my own complete echaust from the header to the mufflers. well they arent really mufflers, more like resonators.

Two mufflers are quieter than one... The reason you see FC's with single exhausts is because it's larger diameter piping, and is less restrictive without the y-pipe...

single exhausts are very loud..

So would a dual exhaust give a nice sound without being "too" loud while giving me improved performance? That damned middle ground again.

yeah, after my roommate put a single on his, he'd wake me up every morning starting the damn thing. lol. I liked the deep tones to it though, when I wasn't trying to sleep.

You will get more performance out of a single - period, they have better flow. You will definitely help out that flow by getting a good header and replacing the cat with a straight pipe. But that all depends on your moral feelings for all of the lungs behind you. lol.

With an N/A car, you're not going to require the flow that a large single offers... If you're looking for a subdued, yet aggressive sounding street legal exhaust setup, look no further than Racing Beat... A large single exhaust on an N/A car will sound tinny and very loud... Racing Beat catback FTW!

Did you just suggest a header for someone wanting a quiet exuahst?

i have an 86' n/a GXL i am running Racing Beat downpipe and presilencer; and Apexi N1 dual muffler cat back. it is a very loud exhaust . its deep sounding . rumbuly sounding. doing just a cat back if you did the same cat-back it would be a little louder than stock. thats if you kept the cats in place. but i am not sure how it would sound since i have not run this cat-back system with cats.

The N1's are what makes your car loud... RB mufflers are very tame sounding... ;)

Right now, imagine a stock exaust with the right muffler cut off. That's how loud I'm at. I want it to get the cops off of my tail about the level of noise, but can't really afford a full cat-back with y-pipe and new mufflers. I don't care if it sounds like crap, as long as it's quiet. How can I achieve this? Will a single pipe be quiet enough?

Stock replacement mufflers will achieve that beautifully... Single pipes are LOUD LOUD LOUD...

no mufflers are loud loud loud.

just go to a cheap-o muffler shop.
the ones around here would fix that for like $60.
or get a stock replacement muffler from farm king for $35, and weld it on yourself.

I'm still wondering if a single will be quiet enough to pass a police noise test (well, all he does is make a personal judgement really). I am almost positive that it'll be quieter than what I have now, but still. If it would, then that'd be what I'd get, but if not then i'll just fix it. I mean, the only reason he said it was too loud was to 1.)pull me over and 2.)he was on a bike with an 3/4 helmet on. Oh, did i mention I live in Michigan, right in the middle of GM country? LOL!

Cut the pipe that is running to the broken muffler, remove muffler, put tomato paste can over the pipe and clamp it on. I did this until my new exhaust came in the mail. It worked good
