Nice sounding exhaust without being to loud and drone
 

Rn I have Gruppe-S UEL header and overpipe with a highflow cat and big resonator front pipe and Invidia N2. I had to put the big resonator in the front pipe to get it more drive able because of how loud and how much drone. I do a lot longer drives now and the current setup can still be annoying. Ive been looking to get a different catback and probably change out the front pipe to a dual resonated because I scrape the big one at times. Im looking for a exhaust that still sounds good and deep, but isn’t to loud and drones. Some exhaust I like are CSGxMXP Touring but not hearing it in person worries me if it will be to quiet. MXP SP but not sure where its at on list maybe to loud idk. HKS Legamax sports S Tail but same as SP not sure on where its at on the list. I think I would really love the ARK GRIP but its just expensive lol. Maybe the AWE Touring but heard it on the 1st gen. Anybody able to help rank on loudness, drone, and quality? Thanks!

Aftermarket front pipes are where most of the cabin noise comes from, short of straight piping, or combining with loud catbacks like the n2. I run an Ace 350 header, stock front pipe, and the CSG MXP Touring 86 catback. Very reasonable cruising levels as you can have a conversation at normal levels on the highway. There is no drone, and comes alive when you put your foot down.

Is their a good aftermarket option thats not as restrictive and still is not a loud in the cabin?

The only aftermarket frontpipe i know of that is stock levels in the cabin is the HKS that you can only get as a part of a set. https://www.hks-power.co.jp/en/produ...haust/db/15165

I don't have any personal experience with the jdl dual resonated front pipe/overpipe, but i have heard people say its the most tame non catted. The catted version is known for having the cats dissolve due to the quality of the cat.

The Fujitsubo dual resonated front pipe has been tested to be around stock levels of quietness without the restriction of a cat:

Thank you!

When I ran that header I tried a few quiet exhausts like the greddy SP and Fujistubo axleback. Both droned worse with a Catted and bottle resonated Aftermarket front pipe compared to stock.
Stock front pipe droned less but still droned which was unacceptable for me. I briefly tried a HKS dual resonated on the stock CB but ditched it due to catless smells. My windows needed to be all the way down or up, any variance would suck fumes into the cabin.

CSG touring is the only CB I would buy going forward, every other CB is a gamble with different headers and front pipes.

Any sound clips? I have a similar setup currently with grupple-s headers, high flow catted front pipe, and greddy sp axleback. It's pretty loud and I'm hoping that swapping the CB would quiet it down a bit.

I have a few clips from various setups.

Anybody running a JDL Ultra quiet or another High flow catted front pipe with UEL and CSG Touring? Not stock front pipe. Wanting to hear it cause this is the setup Im thinking about.

Thanks! Would you happen to have any sound clips with the CSG exhaust with grupple headers?

I do not.
Ended up selling the gruppe-s and swapped to a JDL 4-2-1 el.

I have a JDL 4-2-1 catless manifold, JDL 3" ultra quiet catted front pipe and CSG catback. Its quieter than a Catless UEL, stock front, non-resonated and resonated 2.5" Perrin catback. Its almost stock levels of quiet.
