getting turbo. another muffler thread

I was all set to ditch my flowmaster 3 chambers and buy a set of Dynomax ultraflow #17222 but the guy at summit tells me he runs turbo's on his cars and most people run no mufflers since it won't be that loud. Since I have nothing to go on. What do you think about his advice? He said the Ultra flows will have backpressure I don't want.

A straight though muffler that has too much back pressure?? With that logic the new 4/6 cylinder turbo cars that have full, emissions compliant exhaust systems shouldn't even run!!!

He his correct that turbo exhaust systems are quieter than naturally aspirated engines. I would check out Dynomax Ultraflow Welded round mufflers.

why round muffler Ultraflow over the traditional style. The way my exhaust is set up now the muffler has offset/offset how much modifying would the round style be? I'd probably have to go to a muffler shop for the round style

I only suggest the welded round muffler because it is a little louder than the regular ultraflo.

I made 730+hp through my UltraFlows and I'm going for 900. Nice and quiet too.

I run open downpipe on the street. lol

How gnarly is your engine? Stock-ish engines with a turbo are usually decently quiet at idle. Mine is an HCI forged 306 with a 72mm and louder than my old stock engine build but not nearly as bad as N/A combos.
