As the title states, i'm debating if i should install the exhaust or not because of fear that i might lose HP due to backpressure. Please advise, HELP!!!

 

Its been done on a 525 by a member in Singapore but he never said he lost HP. John go aftermarket. OEM exhaust are restricting and not free-flowing exhaust.

 

Isn't an M5 exhaust suppose to be a higher performance exhaust than my current stock exhaust? My goal is to get a deeper growl and maintain stock like quietness inside and outside the cabin which i think an aftermarket exhaust won't do. I dunno, i'm confused!!! LOL...

 

Can anyone confirm this explanation?

Seems logical and valid but then again i still need other people's opinion.

 

Go with Remus or Eisenmann for aggressiveness.

Tell me this...why would people dump their M5 exhaust for aftermarket John?

 

Backpressure exist. ask vegastrashed and ICEMAN 316

 

I see your point bro but i'm the conservative type of guy!

Now with the explanation from the above link, backpressure should NOT be a concern correct???

 

Depending on how the piping is done to fit the exhaust. AAA should know what to do.

PS: on the exhaust, I hope you are sure on the M5 exhaust is the right one. Here is the cons: it is heavy and second, it may sound a slightly deeper than stock.

 

You want my M5 exhaust? I'm looking at new ones.

 

We had the Eisenhaus Meisenshaft used in stock, but it recently sold.
