[RESOLVED] homemade exhaust?

[GreenT]

if i went to maxi muffler and told them i wanted full 3inch exhaust and to install a muffler, would it be any good. Would the piping be curved or would it be like straight and zigzag. Does it matter if its zigzag. I dont want to spend 500 dollars on some pipe and a muffler.

Ok, I fell more stupider after reading that.

Anyways, as long as it is a full 3" you will be ok. A muffler shop will use press-bent piping though, not mandrel. You will get a little less flow out of the press bent, but if it is 3" unless you are planning on 400+ HP I wouldn't worry about the flow restriction.

If you get 3" press-bent, you will end up with around the same performance as a 2.5" mandrel-bent system. It would also help if you put what kind of car you have in your profile (other than the fact it's a DSM). Finally, when you say you want a full 3" exhaust, you should really specify what "full" is. If you are going to get a turbo-back, you are going to have to get a flex section and a new cat (unless you don't have to pass emissions). Most muffler shops will rape you on those parts so I suggest finding them elsewhere and bringing them with you to the shop.

Yeah, I remember when I first got my DSM. I had no idea what the hell I was doing. Fortunately I've gotten a ton of help off here and saved myself a butt load of money in do-it-yourself stuff and smart shopping. My only regret is the exhaust I bought from Donald Reed in Akron OH. I paid 250 for a 2.5" mandrel-bent, but I got what I paid for.

What the hell. I read some posts and it is nothing but people talking #### to other people. I say something like this for te first time and you guys jump down my throat. In case you didn't notice, I also replied to his message with an answer. Also, I meant nothing serious by my last post, if you couldn't imply by the spelling and grammer, I was kidding.

Sorry, you sarcasm must have gotten lost in the process of posting.

I hear ya. I always like to help somebody out in the best way that I can. Then again I always want to learn something new myself. I didn't mean anything bad by my first post, that's why I included an answer also. I was just joking around a little bit with the grammer. No harm done though.

Well back on TOPIC! I had a muffler shop pressbend me a cat back with a Borla muffler on the end. It's deep and throaty but highly resonating. But i'd still prefer it over some fart can system any day! I bought the parts (except the tubing), cat $50, flanges $10, muffler $120, and took it all to the shop and had them put it on for me for $120. Best damn cat-back money can buy!
