[AC792]

Hey guys --

Just picked up a 2012 F30 335 sport line and want to start adding some mods. First things first, it's way too quiet and I want an exhaust. However, exhausts are quite a bit expensive and I was wondering if I can keep the stock exhaust and add catless DP's? Will that make a difference?

Any info is greatly appreciated!

Yes i strongly recommend starting with downpipes. Car will sound much better with the DP

Hey buddy, take a look at my build thread. Stock exhaust, golf t mod, and HFC DP.... sounds really nice now.

[AC792]

Thanks for quick replies! Now I just need to find some bigger tips...the stock ones are so small. So excited to be back in a 335 and let the modding begin!

Also, can you explain the "Golf Tee" mod? Sounds incredible!

The Golf T mod simply just allows the second pipe (left) to remain always open... instead of only on Sport mode after like 4-5k RPM.

Sounds louder, but its the downpipe that really made it louder.

How do you do this mod? Is it difficult? Also, any DP's that you recommend?

[Livfast335]

Search F30 golf t mod, you'll find tons of threads on it. Many ways to do it.

For the DP's, I chose a High Flow Cat, because a catless will be more smelly and I dont want an angry wife. However the catless will be louder, but I'm more than happy with my HFC.

Challenge, Racewerks are popular typically..but there are others I'm sure.

Awesome, thank you!

A tune like the JB4 will have the golf T mod down via software and you will need it anyways to suppress the CEL from the downpipes, so start with a tune then go with downpipes. ER makes a great high quality set. Either catted or catless.

Is an intake necessary right off the bat as well?

Not 100% necessary but some form of intake mod, whether drop in or full intake is recommended.

Could not agree more. A DP (catless or not) and a JB4 have got to be the best bang for your buck performance mods on this platform.

Thank you much! This makes me think twice about getting a DP...not sure if I can afford to get a FMIC and Chargepipe with it right now!

Then don't. Use Map 1, and hope you don't need a chargepipe. You certainly don't need a FMIC upgrade right off the bat.

Do the DP and JB4 for under $1K and go from there.

That was the original plan. I'll keep you guys posted, thanks for the help!
