Been scrolling through Summit Racing, but can't seem to get any wiser...
My car puts out 98db at 3000rpm, lol. It's just too much, it's not even funny. Keeping a conversation is a PITA.

Been thinking of trying out this one

It has to be straight throu-design and stainless steel.

If you have full exhaust just a muffler wouldn't make a diffrence. What's your piping size?

3" stainless from the turbo and back. 2 mufflers. The mufflers are some super cheap crap, it all came in a set for somewhere around 600$. Thats all stainless!

If there is anyway you wanted to back down the noise, it would have to be getting a pipe made with an E-Cutout or dropping down to 2.5 pipiping.Turbo cars have to have 3'' piping to have flow, non turbo cars max is 2.5 because any higher it would not have back pressure. So if i was you i would look into a E-Cutout. What it is, is a throttle body made into a pipe and ran by a switch to open or close.Open is noisy and close is stock car tone. But to save money and would help just a little on the tone would be a muffler or a smaller tip one!

What car / power you making? 2.5" is will flow plenty good enough for 250bhp so If you can drop down a size as said or buy a larger mid/rear section with more packing.

It's a Volvo 940, 2.3L 4cyl 8 valve turbo in the 250/300bhp region @ the flywheel. I'll try out some better mufflers. Never heard an 4cyl turbo with two mufflers beeing THAT loud before, they must really suck :p

Run the longest resonator you can and a decent muffler. Should quiet it up quite a bit. If that doesn't work. Run a Y pipe and go dual.

I don't even know where to start at with this post. There is no size exhaust has to be for XXXX engine. It depends on the engine, the extent of air flow in/out, compression, and personal preference.

Agreed. Much voodoo magic goes into proper exhaust pipe sizes, especially with tuned cars...
