1990 2.5i 2.5" install tommorrow! (pics now posted)

[JRKOUPE]

I have read EVERY god forsaken exhaust post on EVERY single e 30 forum
and it looks like finally mine is ge ting instlld tomm(Thurs) ! I was hoping to get pre and post dyno pulls to end the age old controversy on what such an exhaust does re power , etc., but it looks like I may only get a post pull due to scheduling.
I will try to post pics during fab/install........it will be, if plan goes: oe exhaust cut rear of our oe x pipe/brace and in frt of oe cat, then the oe duals will be y piped into a 2.5 " single system using a magnaflow ss hi flow cat then on back to a Borla 2.5" SS can. I bought 2 cans, if the smaller one turns out to be tooooo loud Ill put on the larger one. My goal is for a very aggressive sound and hopefully better flow...this is mainly for a DE car that is driven to tracks, some of which have db limits, but overall I want it louder than say an IE or Supersprint, BB,etc. I'm expecting costs incl. all parts to be under 600.....or thereabouts( I plan on using aluminized piping to save cash and because they last quite long on cars that dont see snow/salt). Looks, shine and bling factor were all unimportant, the more raw the look, the better

So did you get it installed today?

How did it turn out?

exhaust....

DONE!...pics to come early next week


I was really antsy upon starting her up after install as I had no idea what my combo of cat/ can would sound like. I went kinda aggressive w/ a smallish MF cat( like 10 inches long) and Borla can(@13" long).........and I must say I was amazed and a bit bummed as it is very very subdued and no more than say 20 % louder than stock(at least my stock).....numbers based on my subjective ear/butt dyno. It does not sound as "tuned" as the IE or SS units Ive heard...its more raw.



It has a mild burble on lift off( I like that) and a mild raspiness/gurgle on initial throttle; at WOT especially above 4500 it has a bit of a wail( me likey) but not overly. Only resonance is mild, and its happening on my rear parcel shelf...no biggie, and it not being a DD I could not care less.




Throttle response is a bit better above 4k and cars pulls a bit better.....nothing earth shattering and I did not expect such anyways.
Total costs w/all parts was under 500!........considering costs/sounds of aftermarket cat backs.......it was a good deal. In future I may play w/ mufflers/bullets to get a more aggressive sound. Feel free to ask any????

looks good, really low key. I bet that magnaflow will burn in a little bit and get louder.
