Exhaust... Bolt or Weld?

[jstrat812]

I was calling around today to get an install quote on my Magnaflow cat-back. I told one of the mechanics that this exhaust directly bolts on. He said that it will come loose and eventually rattle. I would like to bolt instead of weld it on because of resale value.

Any thoughts as to which is better? Bolt or weld?

Huh?

Diy

Bolting won't come loose if you use no nylon locking nuts, with lock washers.

he doesnt know what hes talking about. Bolt it on for christs sake...mostly ALL factory exhaust systems bolt on...what the hell is he talking about?

which kit is it?

[jstrat812]

Thats what I thought.

I have the Magnaflow 16600 system. The tips look amazing!

i just installed mine today....you definitely dont want to weld it.

bolt it on... the bolts expand when heated (ie running your car) and i'm sure it wont rattle... between me, my brother, and my friends, we've put around 30 exhausts on and none of us has a welding machine. everything is good.

WTF! that guy is retard, its actually the other way around lol, if you straight weld it on the exhaust cant move on the donut and will crack and break the welds, now you can install a flex pipe in the exhaust so that dont happen, but then your just straight ghetto riggin your exhaust lol, there is a reason why every oem exhaust bolts on, i suggest just do it yourself and save some money its really not very difficult.

that system really isnt a bolt on anyway...its more of a slide on

If you want the best way go Vband.

yup ide say that system should be doable in a driveway on ramps or jacks. not much to it.

Yep, the type of locknut is called a "Prevailing Torque" lock nut. They are crimped to grip the bolt threads.

wait a minute mine is welded from flex pipe back, i thought welding was the best solution.
