So I finally got around to getting a video together on my exhaust setup. basically cut off the mufflers and put on straight tips. I think it sounds great but I might cut off the secondary cats and install a x-pipe soon. LMK what you guys think!

Ill post up another vid soon when I get a chance to get on the freeway and do another pull.

AWOL

dang, so simple.

sounds good

any performance gain or loss felt?

AKnight55

Sounds good bro

Sounds sick. Do a resonator delete first, I think if you go straight to the secondary's it will get VERY loud. But if you like that, like I do, go for it bro.

I also like the quick U-EE you did at the end of the road

sometimes the simplest things are the best solution haha. Initially I thought the placebo effect was just getting to me but it seems to have helped top end just a bit, I noticed the car pulls a little quicker up to 120 than it use too. I wish my buddy still owned his shop so I could do some dyno runs and see if there was truly any gains but from the feel of the car it does seem to improve.

Thanks andrew!

thanks bro! I use to have a 3.5" turbo back straight pipe on my STi so me and you definitely have the loud car thing in common

only issue im worried about with removing the resonator is it might increase the drone, there is a decent amount when cruising on the freeway. It doesn't really bug me but just annoying when passengers keep asking me why it does that lol. seems like it's impossible to get rid of it on big V8's

Wow...that sounds really good!

Sounds great. I did the exact same thing as you last summer. I had my shop delete the mufflers and initially went with straight pipes to quad round stainless tips. I drove it like this for a few weeks but the drone between 1800-2200 rpm was just too much. I did some research and came across a solution you might want to check out. The pontiac G8 guys are fighting the same type of drone. You can have your exhaust shop weld in a helmholtz resonator and it cuts out the drone about 90%. I had my shop do this and it is amazing. Its basically a dead-end extension about 28-30 inches in length. I had my shop add two where the mufflers were under the rear fenders. Take a look at the "j-pipe" offered by solo exhaust. I had my shop do something similar. Its an inexpensive way to get rid of the droning.

I really like it - have my secondary's removed and having the resonators removed right now - was told it would be ready yesterday should be getting it back today from the shop cant wait!

AMG_RL

thanks for the info, I'm gonna have to look around for more info on the helmholtz resonator. do you have a link or some pics? the J-pipe is not a bad idea but from the vids I have heard they tend to be a bit raspy. I might run a H-pipe between the two sides and see if that level's things out.

that's the setup I had before, trust me you won't be dissapointed. sounds very throaty but it was just too quiet for my personal taste lol

AMG_RL

thanks man! always feels good when some of the O.G.'s give you props hahaha BTW off topic but why is your sig missing?

GregD

The j-pipe is a Helmholtz resonator. If you get the length of the pipe correct it effectively cancels out the frequency where the droning occurs. I didn't notice any change in the exhaust sound at all when we added the j-pipe other than a reduction in droning. We tee'd off the main pipes and radiused a 29 inch section of exhaust pipe for each side so that it would curl up under the rear fender. We then just capped it at the end. I don't have a good picture of my set up unfortunately but it works extremely well. I don't know how much an h-pipe would help since that is essentially what the stock resonator is. I had bad droning with a completely stock set up with muffler delete.

AMG_RL

okay now I see what your saying I thought helmholtz was the brand lol. Ive only heard the J-pipes on American muscle so maybe it's there setup that's naturally a bit raspy thanks for the insight ill have my exhaust guy give this a shot and see what happens! sounds promising

AWOL

Any pics of how it looks? From the back, and maybe underneath?

This might be something I want to try.

AMG_RL

here's some pics of how they look, I recently painted them black since chrome isnt really my thing lol:












and the money shot because I like to show her off :

AKnight55

Looking good... How are you lowered??

chawkins2001

Damn son, that is on the ground, the way I love it. AWOL will approve

dansamg

Sound was perfect - matches some $3k exhaust systems out there.
Ride looks great. I like what you've done

tgoss

Sounds and looks really nice man!

AMG_RL

thanks man, it's lowered on links


yup all my car's are slammed so I don't have to drive fat chicks around hahaha!

AMG_RL

thank you Dan. Just hoping I can get my race car done and begin getting into some fun mods on the E55

Thanks bro!!

Hammer Down

it would be interesting to hear how it would sound with an X pipe

AWOL

Dang, mine is much louder. The resonator must do its job well

AMG_RL

Thanks man, that's next on the list once I get my new wheels installed next week

Yea it's really not too bad until you give it the beans, then it starts to roar. We'll see how the secondary cat delete and x-pipe will sound, I'm kind of experimenting to find the right sound to suit my tastes.

spsinha

Did you ever get around to removing the secondary cats and or resonator? Also, did you cut the tips off your mufflers and weld them to the straight pipes?
