Greddy catback with Gruppe S UEL Header? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

jbsali · 11-15-2018, 01:33 AM

Hey guys, i'm looking to pickup either a Greddy Evolution GT or a Greddy SP Elite for Black Friday and probably a Gruppe-S UEL Header some time next year.

Basically i'm looking into one of the two exhaust systems and can't decide between the two. I'm curious to know if either of the setups will be louder or quieter than my current Muffler Delete axle back. The axleback is pretty loud and would prefer to not get much louder. Loud cold starts are inevitable and something I can live with but trying to avoid drone if at all possible.

I've listened to a bunch of sound clips through youtube but its so hard to get a feel without seeing in person so I thought I would reach out to the community.

Any help would be greatly appreciated! Thanks in advance!

I have a GReddy EvoGT on a UEL and it is quite loud. I like the exhaust, it's just a bit too aggressive for me and the canisters hang low.

I also have the Greddy Evo GT. I personally love the sound but I will also say that it is on the louder side and that's with having the JDL catted header and JDL catted front pipe / over pipe.So If your going for a catless header I would recommend the Greddy SP to keep the sound down other wise it will probably be very loud.

I thought the Greddy SP elite was discontinued? I have the SP Supreme, and it’s very mature sounding but not with a header. The header almost increases the bass of the catback which will shakes houses on a cold start.

i have the SP Elite with Tomei UEL, OP, and dual resonated FP.
not loud at all, very tame and but has a nice growl on throttle.
the OEM mid pipe does a good job of keeping volume down.

any drone?

A fair amount. Not Invidia N1 amounts, but enough to make long trips a bit meh.

The Evo GT with a catless header will definitely be louder than just the muffler delete. The SP Elite might have a chance of sounding about the same volume as just the muffler delete.

I would go with the most mellow catback possible in preparation if you ever want to go catless front pipe (with resonators) in the future.

With having the two cats and resonator I really do not have any drone from the Greddy Evo GT at all. I actually find that when I'm just cruising around the exhaust to be fairly tame. However with the cold starts and when your on it, it can be a little louder. Here is A little clip of my setup so you can use it as a point of reference. However as others have mentioned if you go the cat less it will definitely be louder.
