exaust for e316g

[Aproductions]

should i go with a 2.5 to 3'' downppe and then 3'' testpipe and cat

or full 2.5 exaust?

which is better for a e316g? thanks

well any downpipe is good mines 3 inch dp and 2.5 out the exhaust, for my set up no test pipe just a pipe. for the evo someone else chime in, mines works fine.

I ran 3" all the way from the O2 housing to the muffler, then two 2.25" outlets from the muffler. Works for me.

nice muffler. I'm liking those tips. What kind is it?

Lucas English made his 16g results with no exhaust . . . 3" all the way is better than 2.5", but only if you plan on seeing higher numbers with this turbo. 2.5" woul be fine for say 350whp.

A larger, free-flowing exhaust will allow you more potential power production, but it is more prone to boost creep on the e316g. I have a 3" turbo-back system with high-flow cat and I can't keep the boost below about 22 PSI at the top of 3rd on a full pull. In the lower RPM range below about 5k, I can can hold it to 15 PSI, but from 5k to 7.5k it begins to creep. Rather than spending money on an external wastegate setup to limit my boost, I installed a methanol injection kit to work with the boost creep. I can easily boost to 25 PSI @ 18 degrees timing without knocking on 91 octane.

As I understand, narrower exhaust systems will limit boost creep and ultimate power production, but I've never used a 2.5" system so I can't comment on how well it will keep creep down. As stated, if you're not after every last HP possible out of this turbo, go with a 2.5" system. Good luck.

Using a full 2.5 inch exhaust will absolutely help with boost creep, which is what the E316G is known for with those people using full 3 inch systems. Look at some past posts of Justin's (jusmx141). It will also help with noise suppression, if you're looking for a slightly quieter exhaust tone.

Absolutely makes the note quieter from my experience with similar mufflers.

so you guys dont think i should go 3?

maybe 2.5 until catback?

suggestions

I don't recall. Did I suggest a full 2.5 inch system?
