Suitable Exhaust For 350 Plus Kw Rb26

[Bumblebee]

Im runnin who knows what.. but its 4"s and has 2 mufflers..

massive centre muffler and straight rear cannon.

made 98db @ 4750rpm when it was epa tested.

to drive thou, its not very loud at all and doesnt drone

oh and the power without any problems

Just an update;

Looks like im going to go the custom made route, with either magnaflow mufflers (if theyre available in the appropriate sizes) or custom made mufflers. The centre muffler will be the biggest offset/centre oval design i can fit, and the rear will be an oval also. Ill get the mufflers in stainless and the pipe in mild steel. It'll be 3.5 inch all the way.

Ill probably sell my Trust TR Drag cat back exhaust.

Ill keep those who care posted, as i know there are a few people out there with over 350kw who want a quiet and non restrictive exhaust. Hopefully ill achieve my goal.

how are you going with this? I just ran my dyno up and i need a bigger exhaust, gets real large restriction around 280 rwkw, and looking for around 350 while being quiet and streetable with out picking up defects.

I found the best of both worlds. I think ive posted my experiences with photos somewhere (i dont have time to do it again now), but i used a custom 3.5 inch oval centre muffler made by high tech, and a Magna flow oval rear all with 3.5 inch stainless tubing. Sooo quiet, i dont think a cop would look twice, no drone what so ever, i love it.

PM me if you want specific details such as cost and photos etc. You can also search my recent threads.
