Exhaust Help Please!!!

dc335xi · 04-17-2009, 11:00 AM

Hey guys I wanted to know what you think about this set up. Borla secondary delete pipes attached on to 2 straight pipes running it all the way back to a borla exhaust. Basically its a borla system without the X-pipes from borla. What do u guys think? no cats and reasonator... I'm a bit iffy.

Oh yea another question... what did you guys do with the OEM exhausts after you installed the aftermarkets? I'm thinking about keeping it incase I trade the car in a few years down the road but the exhaust is really heavy and big to fit into any car or truck.

Thanks in advance for your help!

I can't answer your question in regards to the straight pipe or x-pipe, but I know about the stock exhaust, it's actually not that big. If you have a SUV, you should be able to put it in the back with all the seats folded down. Mine is still at my friend's shop, but I will be picking it up at the end of the month. And yes, I'm keeping the stock exhaust, so when I decide to sell the car, I can sell the Borla exhaust and get some money back.

GL!

I wouldn't split the factory exhaust into two separate paths. It's there to help scavenge exhaust from each bank (or in this case, the front 3 vs back three cylinders). I once did it on a previous 6 cyl and the result SUCKED. It tweeted like a bird and you could see drops of water moving in and out of the pipes. Yikes!! YMMV. Good luck!

i'd leave the X-pipe in personally!!

Bimmer335i07 · 04-17-2009, 11:45 AM

Just re-read your post. Leave the secondary cats, go with the x-pipe (delete resonators) and get the catless DPs.

I might be getting Catless DPs soon. LOL! Not sure if I want the exhaust any louder though.

Craig@SupremePower · 04-17-2009, 11:46 AM

Nice but i'd scrap the secondary cats as well!!
