So for you guys that have heard the exhaust in person. What is your honest opinion? Too loud? Ricey? Sounds good?...

its loud but i love it...if i were to go on a long drive i would put in the silencers...and i consider rice when you put on a ridicously loud exhaust that doesnt give you any gains(please refer to the civic that pulls up next to you revving their engine for an example) and sounds bad...in this case 24-34hp and a louder and deeper sound =no rice.

Can you guys tell us how much the cat back weighs?

Also, for others, how much the midpipe weighs.

Turbo XS let me borrow one of their exhausts, race pipe and cat back, for a few days to see if I like it. I picked it up today, hopefully will be installing it today or tomorrow. I'll try to take some sounds clips of what it sounds like with a turbo, and report back on the fitment.

Hell yeah, keep us posted Ryan! Any chance of soundclips?

Any idea if the midpipe mates up to the Greddy SP2 catback without issue?

Thanks!

Ryan, definitely let us turbo'd dudes know your impressions. any chance of getting up to PF Supercars or another place for a dyno run? Would love to see the powers gains.

dd sends...

Ya I'm actually suppose to go back up to PFS for some more tuning since I fixed my boost leak and added a boost controller. I'll ask Ray what the base numbers are which should give an idea of how much extra the exhaust gives.

it sounds beautiful! like the ssr supra 1000+ hp...

awesome! can't wait to hear how it sounds and see the dyno results.

oh yea i'm supposed to be at PFS in about a week....i wont see any stock pulls but i will get a dyno of what the car is getting with the turboxs race pipe and exhaust...so comparing that to 171whp i'll post the dyno's....don't know how much good it will do considering it will be different days and different dyno's but i'll post anyway

im willing to give up my car for however long you need it, if you still need someone. Im not reading through all of the other posts though.

Your too late. He's already got it on 3 NA cars and will have it on a turbo'd 8 soon.

Can some one post how much this exhaust weighs? Is it lighter than stock?

stock exhaust is 39lbs. i think they said it was 25bs lighter than stock. that may be with now cat and with the midpipe.

The exhaust is on. No problems with the fitment. Sounds good at idle, a little loud under part throttle, but not bad, might just need some getting used to. Going from a high flow cat and stock catback to the turbo xs exhaust seems to have leaned out my AFR alot. Scott's wideband was showing AFR in the 15's under very low boost ~2psi. So I didn't push it any harder till I get it retuned, which is Wed. After I get it back on Friday I'll post some sound clips.

The only possible complaint would be that the exhaust tips don't stick out very far, they are recessed more than stock. Some people may like the look though.

Keep us posted bro. That was my complaint in the turbo xs tip thread. Maybe if enough people speak out, they'll extend the tips further. I think that is the only thing that would keep me from getting that exhaust.

All weights in lbs.

Stock CBE : 38.5
TXS CBE: 37

Stock Cat Pipe: 22.5
TXS Race Pipe: 10.5

Stock Header Back: 61
TXS Header Back: 47.5

Thanks,

so most of the savings is from the midpipe. ic...

Thats believable. The stock cat is pretty heavy, and when comparing it to my RP supercat, it feels like stock is made of lead.

Another issue I've noticed is the exhaust piping at the connection to the muffler seems to hang really low.

Does your look like this?

From looking at the picture, the exhaust system really can't be moved up too much or it will hit the cross member. The 3 inch pipe and flange take up quite a bit of space under the RX8. I guess we could look at going to a slip-fit muffler at some point, but I’ve always thought that was kind of ghetto.

Also, have you decided to keep it? I haven’t heard from you, so I’ve not charged your card yet.

Man this thread got long quick - quick question - is there a header in this setup?

no. its a header back system

I don't think its low enough to cause a problem for me, but for those with large suspension drops, I think its possible it could scrape on speedbumps. But maybe not.

I really like how the exhaust sounds at idle though. So far that has been the only time I've gotten to hear it from outside the car. I'm going to richen up the AFR's a bit so I can get on it and see what it sounds like WOT and try to get some sound clips from outside the car. But I'm having some unrelated issues with my car right now that I have to sort out first, its not playing nice.
