I am thinking about putting an M Tech rear bumper on my car and have also been looking on a Supersprint Quad exhaust.

Since I drive a 325i that only has a left side cutout something has to be done.

But if I order the M Tech bumper with a diffuser ment for a 335i then my problem would be solved wouldnt it?

Also, can You recommend any ultra high quality cf diffusors for the E90 M tech?

I see that BMW Performance does one. How does that look. Anyone who has pictures?

No, it won't be solved, because the cutouts for the 325 and 335 quads are different.

I have the mtech rear meant for a 335 but i have a 328xi(single side exhaust). you got it right basicly, but be careful with the supersprint mufflers as they need to clear the battery box on the passenger side rear. You will also need to runa quad diffuser obviously

But if the 335i diffusor wont fint on my 325i, how do I then get a quad exhaust mounted on my car?

Any thoughts?

But if the 335i diffusor doesnt fit my 325i.

Then how do I get a quad exhaust on my car?

it's not all about the bumper/diffuser. the structure of your car underneath is different. you may need to customize exhausts to make fit on non-335s. some vendors may have it in the works... just have some patience.

Buy a non-335 diffuser and have the shop installing your muffler cut the other side.

according to "some forum poster"said.this is the gas breath tank.and this guy have to move the tank from right to left.i was plan to do the 335 exhaust conversion too,finally i decided not going this way after i saw this mod. too much work.and i bought the quad exhaust from MW designs for my car.still waiting for they arrive,and this exhaust can fit 335i diffuser and make it to 335i look.

ahh i see, cause i did a 328 to 335 rear myself, and i also notice that "gas breathe tank" and i had to use the shortest tips i could find and it worked out well. but now i want to get a hamann rear diffuser to get quads and i was worrying about the gas breathe tank being in the way cuz quads tip lengths are kinda long, but if that thing can be move then i'm going for it. :-)

check out this tread: http://www.e90post.com/forums/showth...i+335i+exhaust
they explained their conversion.also,if u can find the 335i mid pipe.i believe there r enough space and fit the two mid pipe out to the muffler exact like 335i.

why not follow the factory modding route to mod our E90 325i to a 335i twin mufflers?

is averigualotu following the parts as needed as per factory fittings of 335i to mod his 325i into 335i twin pipe?
