You’ve got great taste ?? I’ve just acquired the new Gixxer 1000 which peaks around 14K and the Akra sounds ? I just wish the Boxster was a little louder. Just get a Carnewal or bypass if you want a bit more volume. Link to comment Share on other sites More sharing options...

I presume you are happy with the sound ? and did he re--fit the bypassed box ? Link to comment Share on other sites More sharing options...

It does make a considerable difference. I had headaches after driving before... Enjoy the car again now. I've got the 6" x 15 feet which I don't think will be enough (should do one of the back boxes). TShould I do the back boxes & pipes to it as far as possible ?

edc Posted October 8, 2018 Report Share Posted October 8, 2018 Be aware that if you wrap everything you move the heat concentration further down. This can be good for exhaust gas flow and is one of the reasons people wrap or ceramic coat manifolds. But the heat has to go somewhere. If it is all concentrated at the tips make sure you don't melt your bumper. Link to comment Share on other sites More sharing options...

I'm only going to wrap post cat pipe work as that's where the noise is coming from (note USS Harry S Truman went off course during a rather foggy morning in portsmouth Harbour as I drove to Lidl) Hopefully there is enough clearance from the standard twin pipe end & the ground/bumper..

JohnnyUK Posted October 9, 2018 Report Share Posted October 9, 2018 I wrapped both mufflers not the cats. It's not about heat retention, it's about thickening the wall of the boxes to deaden the drone.. Halfords do a 70cm jubilee clip that you can use to cross around the box in a figure eight and secures the wrap. Honestly, it's made the drive pleasurable again.

W7PJN Posted October 14, 2018 Report Share Posted October 14, 2018 I have a Toyo back box off eBay on 2.7 boxster, I fitted it myself. I luv the sound on start up and reviving it through the gears the issue comes as we have all mentioned with the drone. If you wrap the back box does that not take away from the SS appearance from the back of the car? Would wrapping pipework from manifolds to back box and then top of boxes do anything? At 3000RPM it’s getting a bit too much, I have had it on my car 4months with no audible change...... Link to comment Share on other sites More sharing options...

I think the loss of the attractive s/s rear boxes is the price I will have to pay when I wrap the rear mufflers in heat wrap(Monday). As far as I know wrapping the pipes post cat & pre Mufler won/t do much. We do get to keep the attractive twin tail pipes though We are all a victim of buy cheap, pay dear Link to comment Share on other sites More sharing options...
JohnnyUK Posted October 15, 2018 Report Share Posted October 15, 2018 I can't see the wrapped mufflers from behind the car. And I certainly can't see them from the drivers seat! ? Link to comment Share on other sites More sharing options...

KT986 Posted October 16, 2018 Report Share Posted October 16, 2018 I would not discount the inserts ........wrap won't do anything - these will https://www.banggood.com/Insert-Round-Removable-Tip-Silencer-For-4_5-Inch-Tip-Stainless-Exhaust-Muffler-p-1296292.html?gmcCountry=IE¤cy=EUR&createTmp=1&utm_source=googleshopping&utm_medium=cpc_elc&utm_content=2zou&utm_campaign=pla-all2-ie-pc&gclid=CjwKCAjwmJbeBRBCEiwAAY4VVS0EvMOe3ACzPEcRGUAM8BAZ2NGTdnejaVrVuq0YBfqVjyyCGaMtRxoCsZ8QAvD_BwE&cur_warehouse=CN I decided to get a fabricated set up - but was going to pull the trigger on these when I was doing the job The TOYO box is simple to fit , and mine has no drone.............................................................unless I want it !

Halfords do a 70cm jubilee clip that you can use to cross around the box in a figure eight and secures the wrap. Honestly, it's made the drive pleasurable again. So I wrapped both mufflers. The pipes post cat pre mufflers was obstructed with numerous clamps & sleeves so wrapping wasn't reasonable The Result is a nominal reduction of drone. I wrapped about 6M of wrap per muffler & secured with large jubilee clips. I then did a 120 mile round trip up & down to the smoke and it was doable but much more would be a problem I think I will have to go back to stock with a basic bypass in the future A very expensive & very disappointing exercise.

Buying the exhaust and not being absolutely clear to the indie that 4 hours @ £65ph + VAT + Parts wouldn't work for me. Unfortunately he didn't ask & went ahead with the swap. I CAN live with it but for a cost of over a monkey there were better choices out there............... Dented pride thinking it would be a bargain Link to comment Share on other sites More sharing options...
edc Posted October 20, 2018 Report Share Posted October 20, 2018 What was actually done for 4 hours work? That's a lot just to change the rear box. I could understand a bit more of the cats had to come and maybe were changed too but rear box swap alone shouldn't be 4 hours. Link to comment Share on other sites More sharing options...

There were no fixings & first fit the unit was drooping down at an angle. They then fashioned new brackets, clamps & sleeves to get it level & look uniform It does look good just sounds a bit moody !

edc Posted October 20, 2018 Report Share Posted October 20, 2018 Don't meant to put a downer on your experience but I've had the same exhaust and had it fitted at an exhaust place. Of course they fitted new clamps etc U bends reused but I waited for it to be done and was gone within half your time. Link to comment Share on other sites More sharing options...
mattomg Posted October 20, 2018 Author Report Share Posted October 20, 2018 I couldn't get any exhaust place to do it. I think they just took one look at it & thought stainless steel - no way. I tried to explain just fit the k**ker but no luck. I think 4 hours was a bit rich but once it's done there was not much I could do. Makes me wonder about going back though ....... How does yours sound ? Link to comment Share on other sites More sharing options...

Mine was on in 2012. Then a couple of months later with the manifolds. I haven't had that car since 2013 now but prefer the Carnewal. Link to comment Share on other sites More sharing options...
