Figured I would start my own thread instead of hijacking other peoples exhaust thread. No this ain't another ''which catback is best'' thread. Long story short I don't have money to buy a catback at the moment, eventually I'd like to get one but in the mean time I though about replacing my stock LSJ muffler and have it welded at my local exhaust shop. The company I work for sells Magnaflow mufflers and I could get one at a very cheap price. I have been told that the stock exhaust line for the LSJ was 2.25" OD. And I know somebody suggested a 2.5" inlet but we only carry 2.25" inlet. Anyway I don't think that would matter much for the shop I am bringing the car to.

TL: DR

Which one should I get?

MF14821 14" x 6" x 6" - in: 2.25" - out: 4"
MF14827 14" x 5" x 8" - in: 2.25" - out: 4"

Any suggestions?

 

The stock exhaust is all different sizes, but the portion that leads to the muffler inlet is 2.25" o.d.

I was the one that suggested a 2.5" inlet muffler so you can slip the existing 2.25" o.d. pipe inside of it, and weld it on.

You can still but the ends of the stock 2.25" piping to a 2.25" muffler inlet, and weld it.

 

Thank you for clarifying the welding part. Which one of those two muffler would you recommend?

 

MF14827.... The first one looks ricey.

 

Straight thru will most likely make a little more power but the other will probably sound better

 

Wouldn't recommend either...

Just save up and do an over axle set up.
