need some advice guys
I have a 99 c5 and I have it tuned and have a cold air and I recently build the tranny. I bought some texas speed long tube headers with mid pipes and since I want to install them what do you guys think on going with the long tubes mid pipes and X pipe with stock mofflers? Would it still work ? Would it be too much restriction? Opinions welcome

Will it work ? Sure . . but it's like eating french fries with a diet Coke - - leaving the stock mufflers sort of negates the whole thing.
Suggest you watch the form "parts for sale" section and pick up a set of Borlas, Billy Boats, etc . . then you have a complete package.
Just my .02 and your check book !

I'd probably do the whole package if it were my car (even it you had to pick up a used set of aftermarket mufflers). But you certainly can stick with the stock mufflers if you want or if cash was an issue.

I've heard them with stock mufflers. They sound stock at an idle and light acceleration. A tad louder at WOT and heavy load. You'll still feel some power gain, but like other mentioned it's a little choked off.

Will work fine. Stock Cam/Heads the stock mufflers will be fine. you might be giving up a little HP up top but will work fine. I would also agree if you come accross a set of stock C5Z Ti mufflers then scoope them up, you will gain a little sound, performance and looks while dropping some weight (they are super light). otherwise you might look to go aftermarket down the road. Should notice a difference but i doubt it will be a big one (mostly sound). Might consider a bypass mod on the stock stainless mufflers, will make it louder but flow a little extra and should only cost maybe $100.
Bypass mod (these are stock Ti, but can do to base mufflers too)
