3" Piping, not mandrel bent...come inside

[silvachris1]

Ok, I've got a question. I can get 3" pipe bent to fit from the cat back to the muffler for $58. This is the only exhaust shop in town, and they don't do mandrel bends. They'll do 2.5" for $48, but I think 3" would be better since the bends aren't smooth. Anywho, my question, would 3" piping with non-mandrel bends flow better than 2.5" with mandrel bends (I might be able to find a different shop about 45 minutes away). So anyways, opinions on this?

It depends on how big the bends are if they are under 45* then yes it would, otherwise no.

Well, the guy told me that they can make it fairly smooth. I assume they are just gonna make one piece of pipe from the cat all the way to the muffler. From what I've seen under the car, I don't know if there's any angle in the exhaust that's less than 45 degrees. Should I still persue this idea, and at least see how smooth they can make the bends? Sugguestions?

Either way, would you call this a bigimprovement over stock? How bout sound, would you guys think it'll sound better or will it get raspy? Or is that mostly in the muffler.

how can you say there isnt any bends more than 45*??? how about you look again or maybe i need to take geometry again.

[silvachris1]

I didn't say that there weren't bends larger than 45 degrees, I said that there aren't any less than 45, which is what you said would be ok.

[BLLDOGG]

my mistake in the ready, sorry. but im not the one that said it would be ok ;)

[silvachris1]

Doh, now that was my mistake, I meant "You guys said it'd be ok". So, anyways, yall think I should go for the 3" piping? $58 isn't bad ya know.

[silvachris1]

So.....?

i would prolly go 3in non mandrel, or find 2.5 mandrel. the 3in is easy and cheap though, so taht is the route i would go. just depends on the trouble and money u can spend, which is up to you

Dont waste your time..

Well, I got a new cat, and it's not gonna hook to the stock pipe, so either having adapters made and welded, or getting bigger pipes are my options. It's gonna cost me about the same in the end. If I have a pipe to fit, I can install it myself, if I have the adapters made, they're gonna have to install it all there.
