Get out a reciprocating saw and do it yourself! But seriously, make sure the tip looks nice and is where you want it. Then see if you can't shop around for a better price. Make sure any tubing they bend is mandrel bent.

yea I was just thinking of letting them do the pipe and everything then go to autozone / pep boys and get one of those screw on silver pipes to finish the tip

went with the muffler delete

heres a video of the sound.....

http://vid.me/fRpc

I wasnt really going for a loud type of sound, but i can't say i like it or dislike it right now, its just something that has to grow on me over time, but

pros: the sound goes away when passing 4-5th gear which is good (i would hate to hear that sound when going that fast)

cons: it has some type of draw back gurgle only when its idling and gas is being pressed, i can barely hear it when im slowing down though which is good.

inside the car at low rpms it has that low growl but its not too annoying or too loud...

overall I think i like it, my main attempt was looking to have that pipe to stick out the back instead of a downward exhaust pipe which i never liked, i also was going to get a rear m5 bumper so this was needed anyway.

but i did keep my muffler in case this annoys me, other than then, next job is to put a dual tip on the back with a shiny silver finish.

Sounds great, I've actually been thinking about doing this myself recently just haven't gotten around to it. Every video I've seen of muffler deletes on a 525 sound really good. How loud is the exhaust note inside the cabin? Especially when just casual driving around town.

Thanks!, when cruising at low rpms (gear 1-3) it has a really low nice muscle sound to it....

picture your bmw vibrating... but with the sound alone its almost like that, ill post a video or sound clip inside the cabin when i leave for work.

also soon im going to put this on as the tip... to match my "black and silver exterior" look

on the 6 cyl ive noticed a sucking sound when the engine is coasting back to idle rpms? Anyone else have this problem. Revs fine and sunds sweet but that sucking sound when rpms drop is gross.

I have a 2001 540i and last week I deleted muffler and kept the resanators. Straight pipe with the end a bent down. Love the sound and might do a Magnaflow tip.

nice, i think everyone with an e39 should do this mod, it makes it look more beefier with the sound, even if its an I6 still doesn't deserve to be quite as a mouse.

Here's another video of me getting on the highway, 20-70 mph

http://vid.me/x80D

I noticed when doing ~2000 rpms that's when you'll hear that deep muscle sound and anything above 2500 it clears up.

Hell yeah. Sounds the best. Only thing is single tip or dual and I can't find any videos on cutting the bumper.

yea, well the shop i went to, they didnt have to cut my bumper for it to stick out, guess it depends on how low you put your new straight pipe on.

The stock Y piece goes into a 2.5" pipe with a Supercat high flow resonator to a high flow muffler with a turned down 3" tip.
The car is a 535i, M62 3.5L V8 then 5 speed steptronic but now is 6 speed manual.
