i just figured out youtube....so here's my first contribution!

stock 09 135i, BMW Performance Exhaust!

i'm looking at ordering up a JB4 Tuner this week. Possibly some good priced downpipes too but i dont want the car to be any louder. i like the exhaust note now, i'd like for it to stay similiar. but it would be nice to remove some of the lag.
the jb4 alone would help too, but another 20HP cant hurt can it?

don't know how to embed:

If you go with downpipes it will definitely make it louder, and it will definitely reduce lag. You might not like how raspy it becomes with catless dp's.

would i be able to add catted downpipes for it to not be raspy?

my 03 cobra i had i never wanted it to be raspy. i know that some people like it but i do not.

i guess i'll have to do some research when it comes time for downpipes.

i like the sound of the bmw perf exhaust now. the tips are a little on the long side i'd like to cut them to clean it up i think!

i ordered JB4 today! cant wait

a new rear diffuser will shorten the look of the pipes.
if you dont want an aggressive look there are lots of choices from OEM CF($!) to less $ aftermarket CF to less less $ aftermarket
