Are you asking about real world racing gains?

 

thanks mikeb.. i'm planning to get a kit anyway, so i decided to paint it for now.. hehe

 

yeah

 

I noticed mine has a bit of vibration at idle now, anyone else have the same thing?

 

Rikki, that hanger clears fine. It may be my idle which is around 800 RPM. there isn't any rattling, just the exhuast vibrates a little, only when the car is warmed, kinda like a hopped up mustang, but not that severve.

 

Best question might be, can you tell specifically where the rattle is coming from, maybe by laying down under the muffler while the car is running and listening? You can help pinpoint a specific area of noise by using a short length of hollow tube or hose.

 

It's not a rattle. It's the exhuast vibrating at idle, 800RPM, anything higher and it's just fine. Myabe it's just the norm, everthing is tight and there is plenty of clearance by the diff.

 

Have had my Borla for about a week and love it (knew I would, had one on the Miata). Didn't remove wheels or any trim or exhaust ports. But I couldn't separate the cat-to-muffler pipe on the stock system from the muffler, so, assuming I wasn't going to reinstall the stock system, I got my angle grinder and cut it off just upstream of the clamp. After that, everything was slick. Sprayed the hangers with Armor-all so they'd come off easier and then used a big, long screwdriver to pry them off. Reassembly was a snap. No buzz, no rattle, and quieter from inside than I had expected. But definitely a healthy sound from the outside.

 

sorry for my english guy i am a french canadian

i would like install a borla exaust on my rx8 titanium its possible for you to tell me if a adjustement for my rotary is necessairy.

thank you

 

The exhaust simply bolts on, and no other adjustment is needed, to the engine or otherwise. Highly recommended!

 

no adjustment necessary to the engine. i plan on ordering borla in 2 weeks. it's a simple add on, maybe an hour or an hour and a half of work. it'll give hp and maybe save some fuel :P and did i mention it sounds great? i can't wait!

 

Real simple. It was my first time installing an aftermarket exhaust myself and a friend and I had it done in less than an hour. I had to get back under the car to take care of a rattle (documented in other threads) but that was pretty simple also.

 

I hope this helps out...trying to save people with their time by using MINE!

JDM all the way!

 

amen

but not on this forum

 

No way, buy the best you can afford. Do you think you can get a better JDM exhuast for $550? Even $1000? I think not, unless your goal is to have your 8 to sound like a chainsaw.

 

i don't think anyone will ever believe me but i got mine for $350 and one for the mazda sales manager (a buddy of min) for $400.... i ordered it about 2 monthes ago and will get it sometime this thanksgiving weekend

How i got it so cheap is a LOOONG story but if i'm holdng my breath until i have it in my hands!!!

 

KC,

It's a loong weekend so I'm all ears for a good story....do share.

Kevin

Would someone with the Borla please post a wav or mpeg with the new sound of the exhuast??? Pretty please!

Kevin

 

Here ya go Kevin... check out this thread, down toward the bottom of the first page: https://www.rx8club.com/showthread.p...threadid=12631

 

In another message board about 3 months, i found a guy who just got borla as a wholesaler, but before he could be a permanent seller, he had to get $7000 dollars worth of orders. So i asked him how much for the Rx-8? he told me $500 shipped (still a great deal!) so i was in. he also said that if i can get more people to buy, the cheaper mine would be. So i got a bunch of other cars to go with mine and each person i got, it was -$50 from my order. That's how i got it for $350. But the catch was he couldn't ship until he got the complete $7000 order. He just did that 2 weeks ago and has shipped me a couple of my friends' exhausts but no rx-8 yet. i e-mailed him if can order some extra ones but he said he has to sell them alot higher now bec. he didn't make a profit at all!

 

Can someone decipher this for me?

 

what I mean is you might pay more for amuse,HKS, greddy etc, etc
but thats because they are better IMO
