exhaust installation help

Hey, finally got my flowmaster exhaust in, but i have a few questions cuz im new to modding, and have never done exhaust before.

the instructions say i have to cut the stock tail pipe 2in behind the muffler case.

then at the end of the instructions it says "we strongly recommend welding all slip fit connections.

is the cutting really necessary, or can i get it off without cutting? also, how important is it to weld those connections. if i have a shop do just the welding, will it be cheap? what do you guys recommend?

Re: exhaust installation help

You'll have to cut the tail pipes is so you can remove the exhaust through the rear suspension. You can probably try and wiggle it out or remove the rear wheels and springs and all to get it out in one piece (I think this is one of the reasons, but...) I think the bigger reason is because there is no flange to connect the new exhaust to the cats. You can try and fab one up if you'd like.

Of course welding is better, just for general purposes: the slip fittings won't slip and the exhaust will be properly covered so no gases will exit before the mufflers and this will also help the tone of the exhaust. However it is not a necessity to weld them in especially if you secure the fittings properly.

I think the Mieneke around here will weld in exhaust pipes for $20-40, so it shouldn't be too expensive.

Re: exhaust installation help

take it to a shop and let them do it since you have to cut/reweld the mufflers. Plus do you have dual exhaust? if you do not then you only have one muffler and in this case I recommend a catback (stock GT take off is fine) you can remove the stock gt mufflers and put yours in place. There will be a connection modification needed to bolt up a GT catback but its not to bad.
