I dont know exactly, but it's supposed to be one of the best flowing mufflers out there. Look it up on summit, they're not pricey either. I'd like to hear a sound clip of them in a single 4'' set up. Hooker Maximum Flow mufflers is what they're called.

i dont know, I read somewhere on here that they are quieter than the aerochamber at idle and mid rpms, but are louder at WOT. Probably wont be as raspy as a bullet either.

I put a 3.5" system on mine recently. I used a 3.5" Dynomax Ultra Flow Welded muffler in the stock location. Flows 2200+ cfm, sounds good, and it has no resonance. Getting it tuned next week. We will find out what kinda power it is making

They make a 4" that will also work: Part # 17557 - 8¹⁄₄ x 11¹⁄₂ 30"/25" 4"in 4"out, Sport sound - 2200+ CFM - 1000 loss free HP (single) / 2000 loss free HP (dual)

Here is a link to ther .pdf e-catalog. Scroll down to the muffler listings: http://www.dynomax.com/ecat/pdfs/ultraflowelded.pdf

i wanna do the spintech like you as well that or the magnaflow, but i searched on here and some people reported gaining like 60hp after taken their spintech off on the dyno

im not going to add a cutout so i kinda want something that flows good all the time but can keep the dual tips.

but spintechs sound badass hands down ive had them on both true dual setups

got any more pics of under the car, i like to see how people route the pipes

Here's a couple pics of my old Mufflex 4" set up.. I used a 4" single chamber Flowmaster & was pretty happy with the way it sounded.. Pretty deep at idle & having the tip at the back helped alot with interior noise.. It was still pretty damn loud at wot though.

This car belongs to Will, his user name is 02NBMWS6, that is it being tuned at CMS, If I remember correctly he has a FlowmasterY into a 3 1/2 pipe over the axle and two magnaflow mufflers welded together inline. Will is a great guy and always willing to help out, send him a PM and ask for sure his setup.

Oh...and it sounds 10 times better in person!

now im looking into mufflers--ive had spintechs forever and really like them but possibly looking into something else as ill give anything a chance. i just dont wanna choke my motor

i heard a magnaflow--sounds good
http://store.summitracing.com/partde...5&autoview=sku

2nd option but i heard not to do it since i just have long tubes and no cats would be a gmmg, id make my own with 2 medium sized powersticks

3rd option get 2 spintech mufflers and branch the 4in to 2 3in pipes after the axle

other options borla xr-1's but they dont sound that much better then anything ive heard

opinions, sound clips would be nice too thanks
there is one problem with that magnaflow muffler, the core of the muffler restricts down to 3", because that muffler was designed for diesel applications and the 3" core is used to keep some backpressure. believe me i know i have tried it before.
